BUY IT! NOW!
August 25, 2017
Buy this. Do it. DO IT. DO IT NOW. This thing has changed my life for the better. It is very comfortable in hand and the materials are just right. After months of constant daily use, it looks just as nice as the day I bought it. There's very little indication of wear on the buttons and aside from general gunk that sticks around, it is spotless.My favorite feature is the side-scroll, which allows you to scroll horizontally using your thumb. I also really appreciate that Logitech has software that allows you to pair multiple wireless devices to a single unifying receiver, or a single device to multiple receivers. This works great with this mouse, which will remember up to three unique connections which can be easily cycled through using the button on the bottom of the device. The software is free and very simple to use. It also supports bluetooth, which means that you can easily pair it with your phone (Android, at least) or laptop without the need of a separate receiver taking up a precious USB port.Like many other mice, it also has back/forward buttons on the left side that are programmable, as well as a kind of hidden button that is right where your thumb sits. By default, this button is programmed to bring up the alt+tab window switcher in Windows, but you can use the Logitech Options software to reprogram it to do something different - I currently have mine set to minimize the active window when clicked.Another great feature specific to Logitech's higher end mice is the infinity scroll. This mouse takes it a step further by automatically unlocking the scroll wheel when it is scrolled quick enough, allowing you to scroll through massive documents or webpages much quicker than you'd otherwise be able to. You can also manually enable infinity scroll using the button on the top of the mouse. This feature can also be disabled if you're a hyper-active scroller.Battery life has been stellar even when connected via Bluetooth. I use it at least 8-10 hours a day and I can get nearly 2 full weeks on a single charge. Like most everything created in the last 5 years that doesn't start with an "i", the device uses the included micro-USB cord to charge. There is a small indicator on the left side that shows you how much battery is left and shows you when charging is complete.Unlike most of Logtiech's wireless mice, this one doesn't have a built in storage spot for the unifying receiver. Again, not a big deal if you use Bluetooth.My only real complaint is that when connected to Bluetooth, the mouse automatically "sleeps" after about a minute of inactivity and takes a second to wake back up and work again. It has never failed to connect, but it is kind of annoying.Long story short, I would buy this thing 10 times over. I have convinced at least half a dozen coworkers to buy this same mouse and they all love it.
An excellent mouse for a large hand in a three monitor setup
June 26, 2017
This particular mouse was purchased because I have a large hand and its a large mouse. The mouse provides good support for the hand. I don't use any of its advanced features. The mouse moves easily on the mouse pad (a Glorious XL Heavy Gaming Mouse Mat / Pad ) and is quick and precise. I have a three 4K-monitor setup and the mouse works perfectly in this setup. The setup is using for reading, writing and data entry. It isn't used for playing games.It's been 25 days since I purchased the mouse and I just received an onscreen notice that the mouse needed to be charged for the first time since it was charged on the day I received it. Charging is easy; just plug in the cord. The mouse is still usable during charging. I'm using it that way as I write this review. I used corded mice for many years because I didn't like having the batteries run low on older wireless mice. The rechargeable feature of this mouse is nice. I use the mouse seven days a week for I would guess an average of three hours per day. The computer is on for a much longer time however since I listen to background music via the computer; perhaps eight hours per day of total on time. I thus consider the charge life to be very acceptable if it remains at the current length.Charge update: Charged the mouse based on onscreen notice on August 4, 2017. This is 40 days since the last charge.
A bit of an adjustment but definitely a solid mouse
June 26, 2017
The first week of using this mouse, I hated it and was seriously thinking about returning it. I've been using my beloved Performance MX mouse for years. But with the thumb padding worn down to the shell and the mouse wheel refusing to spin down, it had seen much better days. Not to mention the design flaw of the inevitable double click on a single click when it starts to age and is conveniently out of warranty. I had to learn how to position my hand as my thumb kept hitting the little hard plastic part where the battery charging indicator is. The thumb wheel was different and the weighted main wheel kinda freaked me out. But now, I love this mouse. I have charged it once since I've had it where my old mouse needed charging about every other day. The weighted wheel, once I got used to it, is awesome. No more scrolling for days. I can find what I need much quicker now. It feels nice in my small hand. I was a bit annoyed on having to install Logitech Options for this mouse while everything else uses Setpoint. If your going to upgrade from the Performance MX like I did, allow yourself an adjustment period of 1-2 weeks. Overall, a very solid mouse and for the best price available.
Best wireless mouse from Logitech!!!
May 26, 2017
Amazing mouse. So versatile and so easy to customize with their "Logitech Options" mac application. I can customize the buttons within specific apps. Free-scroll wheel feels great and better than the previous MX Performance mouse. Clicks are solid, I especially like the feel of the plus and minus buttons on the side. One thing to note that they're laid out a bit different from the MX Performance so will take some getting used to. Side-scroll is super convenient for video-editing, for example when you're scrolling thru your timeline. Tracking is smoooooth as butter. Ergonomics are on-point for my larger-than-average hands. Good weight, does not feel cheap even though it's made of plastic. Sleek design. Bluetooth connectivity is HUGE for me bc that means no USB receiver and connects to my Macbook Pro pretty much instantly. Does not interfere with speakers or other wireless devices I use.
A fantastic multipurpose wireless mouse
February 22, 2017
 I purchased this mouse as it was highly recommended by many technical people. I'm not a gamer but I was tired of buying cheap wireless mice weren't accurate and felt cheap. After fighting with the cost for a while I finally decided to go with the MX Master.

The MX Master is aimed at working professionals. It has several buttons, which work fairly well for functions in editing programs and other software. The battery usually lasts me a little over a month with daily use and it charges fairly quickly.

Overall I think it's great and I have no real gripes with it.

PROS:
Accurate
Works on multiple surfaces
Looks Great
Comfortable
Awesome adjustable scrollwheel

CONS:
Back/Forward buttons could have better placement
Thumbrest button requires a good bit of force to operate

Amazing Reduction in Pain
July 22, 2017
This is my favorite mouse. I use one at work and after starting to use it my hand and wrist pain just completely disappeared. Maybe 2-3 days of using it I was better. It was amazingly easy to transition to. I'd tried the Evolent ones and I wanted to pitch them across the room. Drove me absolutely bonkers trying to use those. - This one? Amazing.Regarding battery life - I've had mine at work for 7mo now and have replaced batteries 4 times. Small price to pay for complete pain dissipation.Regarding mousepad usage: I had a mousepad with a darker area in the center and lighter colors on the outside (purple along outsides and brown Groot photo in the center) and it would skip when panning over certain parts of Groot's body. Drove me a bit mad so I got a new mousepad (has 3 characters on it and is all blacks and dark blues and reds) and it doesn't skip anymore at all. Just have to be careful what colors on your mousepad I guess. Again, not a big price to pay, just gave the Groot mousepad to a friend and they're happy and I'm happy.Got one for my husband a while back and he uses it on the chair arm and has no issues. Games with it, too, and again, no issues.I'm ordering one for myself for home to trade out for my gaming mouse. I don't use the extra buttons on the gaming mouse, so this works!
I do believe the mouse could rotate the hand another 5 degrees to the right for better ergonomics, but it just might be because
April 12, 2017
After about 8 months of use with my Logitech MX Master ($100.00, price has since dropped), I started getting that all too familiar wrist pain. Especially on the outside of my hand and down the outside of my forearm.This mouse is a $20 dollar jewel. With its first use, the pain subsided substantially. I do believe the mouse could rotate the hand another 5 degrees to the right for better ergonomics, but it just might be because I am a large handed guy. 6'4", built like an NFL defensive back.It took no time to get my hands used to the position it was in as well as the button positions, which all felt natural. The mouse is fairly light, but not a feather, and the construction still feels sturdy and well built. It feels of some kind of rubberized plastic, I am sure there is a term for which I am not familiar.The mouse movements seem to have shorter throws than a typical mouse, as micro movements, such as having to click on a very particular area took a day to prefect. Mainly due to hand position, since your wrist is slightly turned upwards and too the right, certain movements, such as going to the left, now has a slight downward pull when done because it is now done with your wrist. As you can make more movements via the wrist than moving the entire arm due to the positioning of the hand.I own a few other Anker branded products and continually find that despite their typically cheap'er' price point, they are well made and engineered products. And possibly may have found my new "brand"
Updated Review
March 6, 2017
Original Review:I tried this for a couple of weeks and decided it was not the mouse for me. The biggest reason was that it is too big for my hand. I have small hands and I found I was always having to adjust my grip to click or use the scroll wheel. It feels very nice but the actual smoothness has proved to be a problem. My hand is always slipping back and I find myself constantly adjusting my grip. If it were smaller I think I would really like it.Updated Review: The company contacted me about how I like the mouse and I told them what I posted above. They were very understanding and offered to sent me a different mouse for free. I received a new different model in less than three days.This is the new mouse I was sent:www.amazon.com/Wireless-Anker-Ergonomic-Vertical-Adjustable/dp/B018LR04B8/ref=sr_1_4?ie=UTF8&qid=1489187715&sr=8-4&keywords=anker+mouseI love it. The mouse is just different enough to offer a small feel for my hand. I can reach the buttons and scroll wheel easily without having to think about my grip. As a result my accuracy is much better and I can use it in Photoshop which is essential. So if you have small hands and want to have your wrist and arm at a more natural angle this is perfect.
Awesome mouse and even better customer service
January 18, 2016
Received the mouse and after few days of usage realised the mouse has sharp edges near palm touching corner. I emailed customer service with images and they simply sent a new replacement.The mouse is a delight to use. Requires 2x AAA batteries (not included though :( ) . Coming from Microsoft Natural Ergonomic Desktop 7000 the mouse was a natural transition. The mouse is plastic but not a slippery one. As far as functionality is concerned, the mouse is a full sized one. My first finger fits perfectly while the second finger sometimes slips slightly below the right click.Overall, it is a must-have replacement for traditional mouse or for people who are not gamers. Size comparison is with Logitech G700s series.
Anker vs Evoluent. Anker wins hands down!
December 5, 2013
What a fantastic product! I started looking into the world of vertical mice after experiencing some wrist discomfort from the use of a traditional mouse. Of course, the first search hit was Evoluent Vertical Mouse. They were the first to market with a product like this, plus they have the whole University of California academic cachet behind them. For YEARS Evoluent was the ONLY player on the vertical mouse market without competition. As a result, the technology and finish of their product is still stuck in the past. Think those ugly white Microsoft optical mice we all used in the late 90s when optical mice were a novelty. The Evoluent mice have the exact same feel, and even worse tracking capability! In Evoluent's defense, their product does relieve wrist strain, but so does Anker vertical mouse...... for only $20!So let's compare the two products side by side, Evoluent vs Anker. Note that I am just over 7 inches from my wrist crease to the tip of my middle finger. This puts me right on the border for Evoluent between normal and small versions. If you are in the same boat, go the smaller size with Evoluent, provided you don't opt for the Anker.1. SizeEvoluent (standard size) felt a bit too big for my hands. The cheap plastic is also very slippery, making it difficult to pick up the mouse and move it if you are at the edge of the mouse pad (and you do need a mouse pad with Evoluent). Anker fits my hand perfectly. I simply LOVE holding the mouse. It has a really nice rubbery matte finish that prevents your hand from slipping.2. Hand PositionBoth Anker and Evoluent offer the handshake position. I would say that Evoluent hand position is about 80 degrees between table top and your wrist. For comparison, regular mouse would have your wrist at 0 degrees. Anker holds your wrist at about 65 degrees. It is debatable whether 80 or 65 degrees is better. With both mice I felt immediate relief of wrist tension. Going back to 0 degree traditional mouse position feels immediately awkward. It is a toss up between the Anker and Evoluent with a slight edge given to Evoluent, just because they have a bit of science in their product marketing.3. UsabilityThis is personal, but for me Anker wins hands down in this category. Anker feels intuitive right out the box. You click with left finger and right click with the right. The back/forward thumb buttons were also very intuitive for me. This is similar to most Logitech mice. Mouse buttons on Anker have nice rigidity to them. Evoluent, on the other hand, takes some getting used to. It is a big clunky thing that slips out of your hand. Left finger does the left click. But it is, by default, you pinkie and ring-finger that do the right clicking. You can also reassign right click to the middle mouse button, but somehow it feels awkward and you keep pressing the default right click button anyway. Also, it is EXTREMELY easy to accidentally click on Evoluent. Buttons are cheap and plastic, and the scroll wheel is a complete joke. Granted, Anker's mouse wheel is not stellar, but it works well. I must have the newer batch, as I cannot relate to any of the scroll wheel problems mentioned in review. Don't forget Evoluent's back/forward mouse buttons. They are awkward to use at first, but you get accustomed to the arrangement. Matter of preference here.4. TrackingEvoluent tracking is ABSOLUTELY TERRIBLE. I have a black Ikea Galant desk. It's not shiny, just wood with black matte veneer. Everything tracks on it....... except the Evoluent mouse. So you HAVE to get a mouse pad. And be careful, you won't get tracking on every mouse pad, even if it is matte black. This is on a $100+ mouse!!! On the other end of the spectrum, Anker tracks on everything except glass. This is a $20 mouse.In summary, there is not much to chose from in the vertical mouse arena. So get the Anker vertical mouse, get rid of wrist strain... and save Evoluent for the fanboys.
Not perfect, but for the price? 5 stars
May 8, 2013
I bought this mouse because i have wrist and lower arm pain. I can't actively use any regular mouse more than 1h at a time, without getting some pain. Made the switch to a trackball mouse (logitech M570), which was an improvement, but i still had some pains, from the wrist angle (which was not much different from a regular mouse) and from the tendon that belongs to the thumb (since the thumb does all the hard work on this particular mouse). And besides, cleaning the ball every now and then became a chore and it wasn't that precise (esp for games). So i wanted something else, and since only vertical mice were left to try, i bought this one, since it had positive reviews and looked good from the pictures.The good:+ it's comfortable, and this is the most important thing, because so far i can use it for hours and don't have any pains. The wrist isn't twisted like on a regular mouse and i can feel this, for the better. Took me under a day to get adjusted to this angle. An interesting thing about this design is that you feel more inclined to use your whole arm to make mouse movements, which is a good thing, since doing so puts less stress on the wrist. This goes well with the lowest dpi setting, at least in my case.+ i love the placement of the back and forward buttons, on the top of the thumb, where i can access them easily.+ the construction is very good, on par with much expensive mice (Logitech, Razer -which i've used in the past, since i'm also a gamer). The plastic doesn't cracks when i apply pressure, it's as solid as it can be. But it's also light, for a wireless mouse (i've had heavier, from Logitech). The paint is a silky rubbery stuff, like the paint on Razer mice and some Logitechs. We shall see how much it lasts without peeling (a problem which i had with one Razer mouse).+ the buttons don't wobble and the clicks are solid (maybe too solid).+ the tracking is incredible, i've tried everything from bed sheets, blanket, jeans to wood and rubbery plastic, it tracked without issues. Only on glass it didn't work, but that's expected. Impressive.+ it has 3 DPI settings and one blue LED that blinks for every dpi setting.+ the mouse scroll wheel is pretty good, doesn't wobble much and is relatively quiet.+ it looks very good on the desk, very stylish, modern design. All other vertical mice that i've seen looked like something from the '90s.+ the battery life is very good, used it heavily for a week and still works. Works with 2 AAA batteries (not included), i've used two rechargeable Eneloops in mine. No problems.+ fits well in my average man hand (i have 7.5" measured from wrist to the tip of my middle finger).+ the wireless works good, even from 7-8 feet (i use it plugged in the back of my desktop pc, but i can move it to the front, if needed). I don't feel any input lag from the connection, so i can also use it for games (a big plus for me). If you have problems with the reception, you could try another USB port or move it closer, with a usb extension cable. Not needed in my case, but wireless can be tricky in some configurations. YMMV.The bad:- also the general size is good for my hand, my pinky remains on the mouse pad if my hand is relaxed. It has room to sit, barely, but only if i grab the mouse completely and firmly. If not, it drags on the mouse pad. I really wish the mouse shape had a support there for the pinky finger. I can get used to it, but it's an annoyance nonetheless.- the clicks require more force than needed, especially for a mouse that's designed to alleviate RSI and such. The middle scroll button is even harder to press. Mind you, this isn't something out of the ordinary in the computer mice world, but for an ergonomic mouse, this should be fixed (at least the middle scroll button).Other thoughts:Be careful when you move your hand to grab the mouse, coming from the keyboard area. Since it's much taller than a regular mouse, you risk hitting it by accident and throwing it on the floor. The funny thing is this requires more time to adjust than it takes to adjust to the vertical shape.The mouse enters a sleep mode after a period of 4-7 minutes of inactivity. You need to press a button to wake it up. Moving it around won't work. Doesn't bothers me, but you should know this.1 year later UPDATE: it held up well, the rubbery paint is still intact (though it attracts oily fingerprints) and everything else is ok. Also, though i've said i'm a gamer, i didn't said i'm a pro gamer. But as i mentioned earlier, i don't notice any input lag with its wireless reception, but the lift off distance of the sensor is a bit higher than on other gaming mice i had; this may or may not bother you. If you don't know what lift off distance is, then don't worry about it. :)

Excellent, a touch large, flawless connection so far
August 6, 2017
Probably the best mouse you can buy for the price on amazon around $60-$50. I have two one for the office and one for home now. I use them both with bluetooth on the same laptop and never have to reconfigure them. I just turn it on and within a second your up and running. It is surprisingly a touch large for someone who orders large size winter gloves or extra large lifting gloves. The larger size is one of the reasons why I purchased two; so i would not have to put it in the laptop bag and see it take up too much space in a sleeker style bag. The best part to me is the functionality of the mouse with the overall design. This mouse really gives you a great feeling of control. For example, when if you want to see or switch to your background apps just press your thumb down on the jet wing and presto! all your background apps you are running pop up. it's a nice touch. You can also press the top button and switch between a smooth scroll or press it again and it's a click/tread scroll. My favorite is when you start to scroll continuously very fast down it automatically switches to a smooth super fast drop down scroll. This is great when you are in a long thread and want to get to the bottom fast or in a long playlist on spotify or something, no more waiting seconds to get to the bottom, you already there in 1 second. If I had one wish it work a little better when you want to scroll up in this feature, I feel it is not great to scroll up so much.
Flexible mouse with nice features but trouble with Windows 7
May 4, 2017
Overall the construction of the mouse is solid and the design is very pleasing on the eyes. As a mouse, the performance is excellent and I haven't had any issues once it's been paired with a PC.

Out of the box experience is mixed. There's no manual or quick start guide, only an infographic on the inside fold of the box that leaves out exactly how pairing the dongle is done. There's no mention anywhere of the 6th mouse button under the thumb rest, I only found it because rubber molding pops up a little for it and I tried to push the molding back down only to hear a click. I wonder how many people are completely unaware that the button even exists? The 4th and 5th buttons are utterly useless due to their size and placement so far back on the mouse. The "unique thumb wheel" is not in fact "perfect for horizontal navigation and advanced gestures". It would be better if they marketed it as "that weird cylinder that only does something in a few apps, does it poorly, and works backwards from what you'd expect".

I got mouse for working from home so I could control all the devices sitting on my desk and for the most part it's been a success. Unfortunately the button to switch devices is located on the bottom of the unit so it requires two hands to switch which is inconvenient. For whatever reason my Windows 7 laptop cannot discover this mouse when I put it into Pairing mode, my Windows 10 desktop and Macbook Pro find it immediately. Fortunately the mouse has a dongle I can use.
Excellent Replacement for MX1100, But Not Without Flaw
April 19, 2017
I'm a big fan of Logitech mice, and I've been using their products for years. I started out with the MX 1100, which, to my mind, is still the best mouse ever made. This is an excellent replacement for that mouse, and carries over many of its excellent features like a useful dual-mode scroll wheel, good weight, a responsive laser and smooth operation on difficult surfaces like unfinished wood grain.

The first thing I noticed about the mouse was its size. It has a relatively high profile, with a prominent "bump" towards the back of the mouse, so it's good for larger hands. Since it's more aggressively sculpted than many mice, so you might love it or totally hate it, depending on how much you want your mouse to fill your hand.

Definitely superior for palm-grip users, as its cross-section is a little to high for finger grips. The side scroll button is of limited usefulness, and I preferred the orientation on the original MX Revolution, but it's good to see it there anyway. The main scroll wheel has a great smooth feel to it, and it's reluctant to move on its own. The primary fast scrolling mode is great, and the click-scrolling mode is good for gaming. The weight is substantial without being tiring or heavy, and the out-of-the-box sensitivity is decently calibrated.

The back and forward buttons on the side, however, are tiny and easy to misfire. I frequently find myself hitting forward when I mean back, or having to carefully pick between the two buttons with my thumb. And the battery life is not the best, requiring recharging about once a week.
A Fine—But Not Perfect—Replacement for My MX1000
January 4, 2017
I purchased this to replace my well-worn MX1000 laser mouse, which I loved. This model has all the MX1000's bells and whistles, some of which were lost with SetPoint software upgrades that it couldn't handle as the MX series evolved, as well as a couple of additional ones. I am particular pleased with the "fine tuning" of the pointer speed and acceleration of the pointer, which has resulted in more efficient mousing.

There are a couple aspects of the Master that I am less pleased about that will be more or less important to other users. The most obvious one is the Master's size. This is a mouse designed for the average adult-sized right hand. For those with shorter- and stubbier-than average fingers—like mine—this may not be the most comfortable mouse to use. It is substantially larger than the more comfortable (for me) first-gen MX1000 it replaced. This is probably not a good mouse for kids and others with smaller hands. The other feature I have found more difficult to use is the "page forward" button. On the MX1000 the page forward and page backward buttons were separated by the application tabbing button, and so were easy to distinguish. On the Master they are together and I often find myself pressing the page backward button when I wish to page forward. To accomplish page forward effectively, I have to change my grip on the Master. I find this not only to be inefficient but given my particular hand, uncomfortable as well. Fortunately, I use the page forward button much less frequently than the page backward button, so this is a relatively minor problem for me.

Because of the Master's size and design, it is not a mouse for everyone. If it's "on-paper" capabilities are a good match for your needs, give it a test drive to see if it is right for you. It hasn't made me forget my MX1000, which was a great ergonomic fit for my hand, but on balance, the pros have outweighed the cons when I compared it with my other replacement options.
A worthy successor to the MX Revolution with a couple of small flaws.
September 27, 2016
I am a long time MX Revolution fan, and held of on buying this for a while because of the initial poor reviews for OSX. My MX Revolution finally went out to pasture, so it was time to roll the dice - and I'm pleasantly surprised. This review is for MacOS Sierra 10.12.

Pros: Logitech's software appears to have matured, because last time I used LCC it was a mess. This is clean - it integrates into the OSX preferences pane and the configuration panel is easy to use. Customizing buttons is quick and easy and the available options make sense. (I like this software a LOT better than Razer's needlessly-cloud-based Synapse driver, for example.) The mouse itself has that same solid, heavy feel that the MX Revolution had, and the ability to run it corded is always a plus.

Cons: The forward/back buttons on the side could have been designed better, as it's awkward to find the two small slivers with your thumb. I'm sure it'll be better after I have time to get used to it but it's really just a lousy design choice. I also don't care for the vertical side scroll wheel - the horizontal wheel with the same ratchet feel as the primary wheel on the Rev was a lot better.

This would be 5 stars if not for the side wheel and the thumb buttons, but all in all I'm extremely happy with the Master on my Mac. I haven't tried USB Overdrive or Steermouse with it because it does everything I want it to do by default, and the driver is unobtrusive. This is an all around great mouse.

Scroll wheel glitch - like many others
April 24, 2017
Update May 2017: Anker customer service was awesome and provided me a replacement. Four stars for now - if the scroll wheel remains problem-free for a year, then I'll consider bumping it to five.Old: Like others have said, the scroll wheel has become glitchy. One swipe on the wheel is enough to result in the web page (or app you're using) to erratically spazz up and down. This is probably the most-used part of the mouse for me, so it's incredibly frustrating to deal with this.
Gives me pain on the base of my neck. Read update!
April 2, 2017
I've used this vertical mouse for over 7 days and it did not work for me. I think the angle of which this mouse sits on, is not that good. It is not angled enough. It should be more vertical or more "hand shake" like position. It would not really hurt my wrist but instead it would hurt my trapezius, the muscle at the base of your neck between neck and shoulder. Why? Due to the fact that the material of the mouse is way too slippery (especially if you have dry hands) and you don't have enough grip on it. So by having to hold it tight all the time, after a while tension builds up along your arm all the way to the trapezius. By the way I have big hands (8" or 20cm from wrist to tip of middle finger) and yet due to the bad grip on this mouse I would get pain on the base of my neck. The concept is good but needs improvements...I'm going back to the regular horizontal mouse. Fortunately Amazon took it back without problems and refunded me in full.Update 5-16-17:Following my original review, Anker contacted me about my issue with the mouse and gave me a great customer support by shipping to me a new smaller mouse at no charge. The new mouse is basically the same but a bit smaller. I think it's the previous version...The smaller size helped me to better handle the mouse but unfortunately as I wrote on the original review, the material which the mouse is made of, is too slippery for me as I have always dry hands due to my job. Like I suggested to Anker, I wish they would make a version of it that is made of a more rubbery material so I could have a better grip on it.I gave two more stars to Anker (from 2 to 4) for the great customer service.
Perfect Mouse
March 8, 2017
I've come to love this mouse. I thought I'd give an ergonomic mouse a try after having some wrist problems. My job is >75% at a computer and previously used a typical mouse and an ergonomic mouse pad with wrist rest. Even with the mouse pad, my wrist was aching to the point where I considered wearing a wrist brace throughout the day. After switching to this ergonomic mouse, my wrist feels much better.As you're probably aware, you hold this mouse sideways. I thought it would be awkward to get used to, but it probably took only 15-minutes to be totally comfortable in using the mouse. Tilting my hand to the side feels more comfortable than the alternative, and I like that I could ditch my mousepad (since I didn't need or want the wrist rest anymore). The mouse has an auto shut-off that activates after (I'm guessing) 10-minutes so as not to drain batteries. I've only had 6-weeks, so I'm not sure how long the battery will last. It's a standard two button mouse with a button wheel, page up/down buttons, and a weird button on the top that I've never used or looked into.It probably deserves 5-stars, but I'm giving 4-stars for two primary reasons: (I) it's not a loud mouse, but I do prefer silent mouse buttons and wish these were more quiet. (II) I prefer hard wired mice, as the response time and accuracy is better, and I don't want to have to change batteries periodically. I couldn't find a hard wire version of this mouse though.Overall, ESPECIALLY for the price, this mouse is unbeatable. I highly recommend it if you're looking for ergonomic alternatives to your traditional mouse.
Very nice, but for me the scroll wheel was too far away
February 23, 2017
UPDATE: Anker, who is a model for how companies should take care of customers, sent me a model AK-A7809012 to try instead. I've been using it long enough now and can give it a 5-star review. My advice is that large hands, this model is great. For average to mall hands, get the AK-A7809012.No question that this is better ergonomically for me. After using this for an hour, I can't believe we did not design the mouse like this from the start. So much more natural for the arm and wrist. Like any Anker product, it seems well made and the styling is nice.But I have to take half a star off for how smooth it is underneath. I am sure in time the pads will roughen a bit, but for me I could not find a mouse pad or surface where this would not slide too easily, and as weird as I'm sure that sounds, the mouse became difficult to use. I put my keyboard tray at a slight down-angle (maybe 5°) and I noticed it sliding away from me under its own weight occasionally.I took off a full star, though, for the scroll wheel position. The wheel itself is great - very nice to use as a button, and the scrolling action is wonderful. But it's beyond the tips of my fingers. I have to sort of reach further around and stretch my fingers straight to use it. I have average man-hands (size L or XL glove generally), but I use the scroll wheel *a lot* - like all the time. I scroll through documents, I zoom in and out with it (using a key modifier) and I click it to paste in the terminal or in documents.So I need the scroll wheel to be under my fingers all the time, and for me, this mouse was just too big. For comparison, I use a Logitech M705, and the scroll wheel is in the space bridging the middle and distant phalanx (in the bend of the last "joint" of the finger). On the Anker mouse, I can just touch the scroll wheel with the tip of my middle finger, but it's too far away to press or scroll without adjusting my grip, and unreadable to my index finger.I'll see if I can give it away to someone with larger hands or longer fingers - it's too nice to simply return.
Needs pinky rest; Consider new model
December 5, 2016
This mouse fits perfectly in my medium sized hands. The problem I have is how slippery this mouse is. If I relax my hand, then it slides down the mouse so that my third and pinky finger slide against the mouse pad. There are only two ways for me to use this mouse comfortably:1. Claw grip: my preference for mice has always been a palm grip because it feels natural. But as I explained above, the mouse is slippery. To get around this I have to claw the mouse and even then I still have to hold my wrist in an unnatural position.2. Double up: I have always used one finger on the left clicker and one on the right. But to prevent my fingers from hanging off the edge of the mouse I have to rest two fingers on the left clicker. This method is more comfortable but I do find myself accidentally right clicking when I try to use the scroll wheel (maybe I'll get used to it).All in all, the mouse works great but the lack of a pinky rest, along with the point near the dpi button, makes using the mouse uncomfortable.One final note: the mouse has a convenient slot underneath, so you can store the usb dongle.UPDATE & COMPARISON: I added one star for the awesome customer service.A few days after I wrote my review I was contacted by customer service and they offered to let me try the new model (Wireless Mouse, Anker Ergonomic USB 2.4G Wireless Vertical Mouse with 3 Adjustable DPI Levels 800 / 1200 / 1600 and Side Controls, Black). There are some differences/similarities between the two which I will list below.1. Left/Right Click: The new model requires slightly less force to click - likely because it isn't as "vertical" as the older model - but the difference is really insignificant.2. Scroll Wheel: I'm tempted to say that both models have the exact same scroll wheel with different mounting, and there is one minor as well as one huge difference. The minor difference is that on the new model the wheel is sunken deeper into the mouse than the old model (this can be seen in the pictures I've uploaded). The huge difference is that the scroll wheel on the old model requires a lot more force to click compared to the new model. Using the old model I often found myself missing or accidentally scrolling when I tried to press the scroll wheel, but on the new model it's very natural.3. DPI Switch: For both placement and button quality, the old model surpasses the new model. On the old model, using the DPI only requires you to slide your thumb up (and the button is impossible to miss), while the new model is a tiny button behind scroll wheel. This shouldn't be a problem unless you're constantly using the switch.4. Forward/Back Buttons: These are completely different on the two devices. In terms of responsive they are, the buttons on the new model can't even be compared to the old model. It only takes a very light pressure to use them - it's so easy you can click the forward button with the tip of your thumb and the back button with your inner thumb knuckle without even trying. On the other hand, the new model requires more force but it isn't "too much" force, so you don't have to mind the buttons if your thumb is resting on them and you don't have to try too hard to press them.** This may just be the item that I received so I've "starred" this difference. The back button on the new model feels flimsy and ready to break. It feels like there is some kind of spring pushing up on the button, but that spring is off center such that one side can be depressed much further than the other. This gives the button a "cheap" feeling.5. Shape: As someone who'd much rather rest their hand on their mouse as opposed to holding their hand in a certain position, the new model's shape dominates the old model's. Honestly, it's because the new model doesn't have the pointy edge. Without the pointy edge there are much more ways to hold the mouse so it's easy to find a comfortable position. That being said, the new model is also slippery and doesn't have a pinky rest (disappointing), but it's still much more comfortable than the old model.6: Size: The mice are roughly the same size, but because of their shapes, the new model "feels" smaller in my hand.
Looks like I'm sticking with Evoluent...
July 16, 2014
I have been using an Evoluent VM3 and VM4 for a few years now. I'm in the market for a wireless one, but thought I would give this a shot based on the reviews here and the major price difference. When holding the Anker mouse, your hand sits at more of an angle. This is compared to the Evoluent on which your hand rests vertically. The grip isn't too different though and feels natural to me. The mouse has a rubbery texture which is a nice touch. It is smooth and provides just enough grip. The mouse is very light even with the batteries inserted (batteries not included, btw). Unlike for others, the light weight isn't a problem for me. There is no 3rd mouse button where your ring finger and pinky sits. This is a good thing, because with my Evoluents I had to disable the 3rd button because I found myself accidentally clicking it. I have no problems with the tracking and find the precision to be sufficient for my needs. Because of the light weight, texture, and angle my hand rests at, I feel that I have more precise control compared to the Evoluent.The big problem, which is a deal breaker for me, is the heavy mouse buttons. I read other reviews about the heavy buttons thinking that they were exaggerating, but unfortunately it's true. Both of the mouse buttons are heavy and harder to press. Not just compared to the Evoluents, but compared to Logitechs and any other mice I've used as well. Every time I click, I end up not pressing hard enough. I find myself having to think about clicking the buttons harder. It just doesn't feel right and feels unnatural. It's too bad because I like everything else about this mouse.UPDATE 08/18/14:Adding one star because of Anker's superb customer service. I was contacted by Anker to assist with my concerns. I tried a replacement mouse to see if the mouse I had was defective, but unfortunately it was not. Anker was understanding and we came to a mutual agreement on the product. I hope that in their next version Anker will address the concerns I have, because I will most definitely try it again because of their service!

Excellent specifications, but falls short in usability
June 3, 2017
I have been a user of Logitech keyboard/mouse for 10+ years now and have been using MX series since the MX1100. I switched to Performance MX when it was released and been using that for past 5 years (2 of them due to button failures). The 2nd one gave out recently and bought the MX Master as replacement. The shape of the mouse have been changing since MX1100 and with every revision, the mouse is becoming leaner. I still have a working MX1100 and prefer the fit of that better than the Performance MX and MX Master.
Pros:
1. Mouse feels solid with a good heft to it.
2. Built-in batter lasts much longer than the AA battery in Performance MX. I'm a heavy user (10+ hrs a day) and Performance MX battery lasts only 4-5 days using a rechargeable Eneloop battery. I didn't have to charge MX master even once after 2 weeks of use and based on the battery estimate, I would guess it would have lasted for at least 30 days for me.
3. New software Logitech options is pretty good compared to Set Point.

Cons:
1. Doesn't fit in hand as well as the older versions of MX (Performance and MX1100) (May work for someone with smaller hands). I started having wrist pain with couple of days of use.
2. Didn't care much for the thumb wheel. It has a mushy feel while scrolling with no feedback(ratchet). So, doesn't give controlled operation for say, zoom/volume controls. It always ended for going over or under when scrolling.
3. The buttons next to thumb wheel or not positioned well. It feels awkward to use. I prefer the placement of these buttons in Performance MX or MX1100.
4. Logitech options Software - It doesn't support older devices. I have a K800 keyboard and that still needs the Set Point. Logitech should have one software that supports everything. I hated having to use both of them to set options for keyboard and mouse separately (and they have a annoying message every time I open them saying one of the plugged in device is not supported).

Overall, the mouse sounded very good based on specs (with speed-adaptive scroll wheel, bluetooth, connections to multiple devices etc.). While I do believe it is technologically advanced compared to previous versions, it failed in the usability and ergonomics compared to earlier versions. I have returned this mouse and gone back to my MX1100. I will use it as long as it lasts and probably get a Performance MX when it fails. My wishlist would be a MX1100 with a nano receiver.
Almost perfect
May 26, 2017
The things that stuck out to me from this mouse is the ergonomics, it's ability to work on glass, the programable buttons, and dual bluetooth/unifier connection. Below are my pros and cons.

Pros:
- Internal battery
- 6 programable buttons
- Works on glass
- Ergonomic shape
- Bluetooth/Unifying receiver

Cons
- Scroll wheel
- Loud
- Matte texture

The things that I don't like about this mouse are mostly trivial but they're things I'm not a big fan of. The soft texture feels a bit odd on the palm area. I'd prefer if the soft texture was smooth plastic. I don't like how loud the scroll wheel is. It goes to free scroll mode when you scroll down and the locking mechanism gets annoying. If it wasn't for the texture and scroll wheel, this mouse would be a 5/5 for me.
The good, the bad, and the... wait, where's the dongle...?
March 23, 2017
<|> Comparing this to my Gs (G700 & G700s):
=> It is a near seamless transition between the two for fit and movement. Response time and latency are great for workstation/productivity tasks and very good for "less than professional" gaming. Wireless response time is not noticeably different than when wired.
=> The detachable cable (like the Gs) is nice, but I would prefer a design that puts less stress on the plug though. Over time, this can cause intermittent connectivity issues.
=> Battery life is just as good, if not better, than the Gs. I get several hours of continuous use on one charge without a noticeable reduction in performance.

<|> Subjective Differences:
=> The Gs change DPI using buttons to cycle between profiles. The MX uses a thumb roller for DPI change. For precision gamers and designers who need predictable interactions, this is a potential nightmare since it directly changes the DPI instead of cycling to preset levels/profiles. For casual users, this will probably be a beneficial feature since it makes it easy to make minor DPI adjustments on the fly.
=> The buttons are good, but not great. There is a tactile and audible click when the switch activated, but there is more of a travel distance than I personally prefer.

<|> Cons when compared to Gs:
=> The sticky feet on the bottom of the mouse can cause problems. The laser works great on the surface of my desk, but the feet grab hard, so fluid and precise movement is near impossible. Using a fabric or textured mouse pad/mat nullifies this problem entirely without noticeably reducing accuracy, even with precision gaming.
=> The reduction in the number of available buttons is a minor concern, depending on how you use the mouse and if you need the extra buttons.
=> The battery in the Gs is easily accessible, and thus, interchangeable. That makes it possible to carry spare batteries for quick change if needed, or for easy replacement when the battery expires. The MX battery is not easily accessible and is also proprietary. This, to me, is a major design regression when compared to the Gs.
=> The Gs have a compartment for hiding and carrying the USB dongle. This makes it easy to carry and keep track of it. The MX doesn't have any way to hide/carry the dongle in the mouse. This makes it very easy to lose it. Again, a major design regression.

<|> Conclusion
Overall, this is an EXCELLENT mouse for under $100 USD and good for workstation tasks, but serves to show that Logitech mouse design is actually getting worse rather than better.
A True Successor to the MX Revolution (Update: Mousewheel drifting, Do Not Recommend)
April 6, 2015
I have been using Logitech's MX Revolution for about 5 or 6 years now, unable to switch to the successors of that particular mouse because of suggested downgrades. When the MX Master was announced and Revolution fans suggested that it could be the worthy, true successor to the MX Revolution, I pre-ordered it. Well, the mouse arrived yesterday and though I've only been using it, here are my initial reactions.

First, I do think that this is a worthy successor to the Revolution, though some things have changed. There aren't any major drawbacks in just ~24 hours of use (mostly doing web development, general browsing, on both a PC and Mac). I'm going to update this review as I use the mouse more, but here are my first reactions.

- The mouse is slightly larger than the Revolution, about the same width but slightly taller. This is fine and it's been comfortable to use coming from the MX. The contoured edges are a nice touch and don't give me a 'sweaty hand' like other contoured mice have in the past.

- The ratchet scroll / free spin scroll wheel is the single most sought after feature of this mouse, and it has a toggle button where the Revo's (useless) search button used to be. I will almost never use the ratchet click because I've gotten so used to the free spinning wheel and can't find any use for a slower scroll now that I've been using free spin for half a decade. This can also be controlled via software, so you can set it to free spin as all times and re-assign that button if you'd like. The horizontal scrolling on the scroll wheel (tilting it left/right) has been removed from the Revo. It's been replaces with another function (see 2 paragraphs down).

- Which brings me to the software called "Logitech Options" which is much improved. It's obvious that Logitech invested in this area over the years, as their old Logitech Control Center software for the Revolution was really lousy, even in 2009 it felt dated and clunky. The new application is light, only took a few seconds to download, and it highlights the areas of the mouse that you can tweak. Everything was clear and made sense to me, where as the Revo's software felt like features were hidden in bizarre menus or given annoying trademarked names so you really didn't know what they did or meant without trying them out.

- Back to the hardware, the jog dial has been replaced with a small north/south wheel on the left side of the mouse that has the right amount of tension. Out of the box, this is used to horizontal scroll, which I find only passingly useful. There just aren't that many applications (for me) where I regularly use horizontal scroll intentionally. The software allows you to re-assign this to cycle through your tabs or applications (similar to ctrl + tab for Chrome, or alt + tab for windows). The tab scrolling is nice and it works but it's not as immediate as the jog dial if you went through the work to re-assign that. But so far, tab scrolling works in Chrome, SublimeText, Dreamweaver CC (2014), and Photoshop CC (2014), which is much more support than the old jog dial implementation had. I haven't tried a tabbed piece of software that doesn't work yet. Even Lync client for Windows (with vertical tabs for conversations) works, so I'd imagine this is fairly universal support.

- One drawback is the two tiny buttons next to the jog wheel which replaced the back/forward buttons on the old Revo. These buttons are difficult to press and feel spongy because they have this diminutive design that doesn't feel great. It's tough to differentiate between them at first. Out of the box, these control back/forward in the browser and you can't map them to too many different commands (like switching tabs for instance).

- A strange new feature which I'm still undecided on is this gesture button. So, I heard this described and I wasn't sure how it would work. On the base of the mouse, say where your thumb would rest, there is a button that you can press (but it's flush with the design of the mouse) that allows you to quickly move your mouse in a particular motion to do some command. Out of the box in Windows I have it set to snap my windows left/right, and on the Mac I have it switch desktops. This works, but it's... not intuitive and honestly feels like it takes more work to feel for this button and then quickly move the mouse. One thing Logitech did well is that your mouse cursor "locks" in place while this button is held down, so it makes it more intuitive in knowing whether you're doing some gesture command. It's a nice attempt to build gestures into the mouse but it doesn't quite work like how the marketing materials want you to believe. The good thing? This can be remapped to do dozens of different commands.

- The mouse can be assigned to control up to 3 devices, which is great. I use a PC at work, I have a Mac Mini for development at home, and then a MacBook Air for browsing/light use and it's nice to have this mouse work on all 3 devices with just the click of a button (a device selector is flush with the unit on the underside).

- Syncing via bluetooth on OS X Yosemite was flawless. Connecting to the wireless dongle (the tiny one that Logitech has used for most of their devices) was equally intuitive.

- The device charges via a 3 foot USB cable which can also send a connection over. Seems like it works, not much to report here.

- Other things like precision of the pointer, etc., I'm not the best to report on... Seems fine? After years of use the MX Revolution would skip frames on me on my PC, but I think that's more related to a not-so-great work computer, rather than the mouse... but so far, so good on the MX Master. I can't comment on battery life yet, I've been using the mouse for less than 24 hours.

Conclusion:
So far, I would give this mouse 5 stars. That doesn't mean that it's perfect, for instance the gestures could be improved and I would like it if the software let you re-assign every button to do anything... As it is, some buttons can't be re-assigned to do *everything* (like switching tabs with the back/forward buttons). But, thus far, it is certainly a worthy successor to the MX Revolution and one that I have easily transitioned to.

As I continue using the mouse, I'll continue to update this.

** Update 48 Hours Later **

So, with 48 hours of fairly heavy use, the first noteworthy adjustment I made was turning *OFF* the "Smooth Scrolling" in the Logitech Options application. I was noticing that very, very subtle movements of the wheel caused a page to scroll up or down, which was only mildly annoying on a typical scrolling website, but made using any sort of mapping site (Google Maps, etc) or applications where the wheel performs some command (photoshop) frustrating. In fact, I noticed that if I just moved the mouse rapidly, the page would slowly scroll down because the mouse wheel was so sensitive with smooth scroll turned on. I turned this off and now I am happy to report consistent, predictable scrolling and no noticeable change to how it feels when I do scroll intentionally on a page.

** Update 10 business days later **

Battery life is still kicking on 2 Bars after the first full charge. I also turn it off at night when I go home (and on weekends), but use the mouse heavily from 9am to 5pm. Not sure how long the final 2 bars will last, but so far, seems like strong performance.

** Update 6+ months later **

I have two of these mice now, one for home and one for work, and I've noticed mousewheel drifting when the mouse is set to the free spin option. It's more noticeable on OS X than on Windows probably because OS X is more sensitive to track movements. Basically, on a free spin, the wheel will rebalance itself by tilting back a fraction of a spin... This can cause a page to drift back up or down in a specific direction. It's hard to explain so I've added a video of it. Looking this problem up online, Logitech has suggested turning off the freespin if you're experiencing this, but that isn't a solution to me. Dropping a star because of this annoying problem.

(Also, sorry Amazon's video compression is terrible so you can't see the details of this, but towards the end of the video the mouse wheel drifts backwards from the direction I was spinning)

(Updated 1+ year later)

Reducing the review to 3 stars because the drifting has seemingly gotten worse instead of better. I was willing to give this a chance but I'm having drifting issues on both WIndows 10, OS X, and Ubuntu. The issue is very annoying and happens almost every time I'm using the mouse. I'd actually not recommend this mouse because the issue has seemingly gotten worse either with age or with new driver updates.

August 30, 2017
Edited to add: I added 2 stars purely for customer service. Anker reached out and offered to send me a new mouse, which they did. The one they sent is a different version, no shark fin, and it is very smooth. None of the drag issues of the shark fin, at least as far as I can tell after one day's use. I tried to find the version they sent me on Amazon, but couldn't locate it. My final star reviews would be as follows:Shark Fin version: 0 starsNew mouse: 5 starsAnker customer service: 5 starsEdited again: Anker CS emailed me the link to the second mouse, which I've now been using several days and absolutely love. Here is the link to the mouse I would give 5 stars to: https://www.amazon.com/dp/B018LR04B8/Original review: 1 star I was excited to get this mouse but it seems really glitchy. It doesn't drag smoothly at all. I have to constantly jiggle or tap it to get it to move the curser in the direction I want it to go. I've tried it using two different mouse pads as well as just the desk top but nothing helps. And all the extra wiggling and tapping makes my wrist hurt even more.
Would have given five stars but...
June 19, 2017
I purchased this wireless mouse to use as my "in-office" mouse for my work laptop. I have two; this one, and one that has a slightly more sturdy construction (though I don't like it as much as this one) to put in my laptop backpack when I'm out of the office.I would have given his mouse five stars; it's sleek design makes it much more comfortable to use than my clunky spare. However, I have two issues with it. The first time I went to replace the batteries, the cover for the battery compartment broke. It still goes on, but there is a crack in the thin piece of plastic towards the back of the mouse (see picture). My second issue is that, after three years, it suddenly randomly stopped turning on. Sometimes it works, sometimes it doesn't, very hit or miss, which is sad because it is my favorite of my two mice. If it were a bit cheaper, I'd say I was pleased with what I paid for, but considering I spent $20 on it, I expected more than three years out of it, especially given that I only use it for about 25% of my workday, as I am often working out of the office. I do LOVE the design though. I just wish it were more durable.
OK wireless mouse. Poor Ergonomics.
May 22, 2017
Functionally, this mouse works as a wireless mouse. Connection to the computer and mouse operation are reliable and consistent. However, the buttons require more pressure than a typical mouse. Pressing the center scroll wheel is very stiff and uncomfortable. My primary software program is AutoCAD and requires regular pressing of the scroll wheel for view manipulation. For this reason alone, this mouse is very uncomfortable to use with this program.The Back/Forward thumb buttons are slightly further back from where my thumb wants them to be. This means that everytime I want to use these buttons I have to re-orient my hand on the mouse.I'm still using the mouse with general applications hoping that I get used to how my hand needs to hold this mouse to work, in the off chance that this becomes less of a hassle, I'll update this rating and post.In the end I'm very disappointed that this "Ergonomic" mouse has very inferior ergonomics vs a standard mouse. I guess that is to be expected for a $20 mouse..?..Revision:While this generation of mouse might leave something to be desired, Anker's customer support is absolutely top notch! In the end they sent the newer version of the mouse (model # TM156G) which works much better with my hands. The buttons on the newer mouse feel much better and require less pressure, making the overall experience similar to a standard mouse. The forward/back buttons are still just a bit too far back, but overall much much better. This is an ergonomic mouse that I will actually use. I'm upgrading the review to 3 stars. It would be 4 for the newer mouse by itself, if my path to this point didn't go through the previous generation product... (if there was a rating for Anker customer support, they would get 5+ stars!)
Just okay
January 28, 2017
The position that the hand is in with this mouse is very comfortable compared to a standard mouse as the wrist is not twisted. The pain I get from using a standard mouse is gone.The build quality is very good and the adjustable resolution is helpful when working on things that require more detail.The drawback I find is that the buttons take more force to operate and often cause movement of the mouse when pressing the button. This requires one to redo the errors that are made due to the movement. Also the forward/backward buttons need some redesign. The back button is fairly convenient, but the forward button is in an awkward place which causes problems as operation of these buttons requires the user to squeeze the mouse causing it to move off position.The mouse would also benefit from a hand rest on the right side so that you hand does not drag on the mouse pad.The scroll wheel does not have side-to-side scrolling, but by pressing the wheel it activates the windows scrolling option. One other problem I have found i that with the height of the mouse, I find I am constantly knocking it over or off the keyboard shelf when I reach for something on the desk. Maybe after more use, I will get used to it.Overall, I believe some tweaking of design would really improve this mouse. For only $20, it is not a bad deal.
Surface needs overhaul to aid in control/handling.
February 20, 2015
Great concept at a great price, BUT needs a serious overhaul with surface texture to aid in control. The mouse wanted to walk on you. It constantly creeps out of your grip. I added the tacky tape to the mouse and it is now perfect( see pic). I would have been willing to pay another $15 so I would not have the constant feeling that the mouse is walking out of my hand.
Evoluent VS Anker
May 27, 2013
July-9-2016 update:It has been three years since the original review, I have to downgrade it to 3 stars not because the build quality which is great. But ergonomically speaking, it just didn't work for me. During a extended business trip when I had to use this mouse for 10 days and my wrists was feeling the pain. The pain went away after I switched over to Evoluent mouse. I believe it has to do the the form factor of this mouse. Since then I've bought Wireless Mouse, Anker Ergonomic USB 2.4G Wireless Vertical Mouse with 3 Adjustable DPI Levels 800 / 1200 / 1600 and Side Controls - Black which is much improved. I would recommend it over this one for casual use. Opinions in the original review still stand.Original Review:I've been using Evoluent vertical mouse for over 10 years, it has saved my wrist. Then came this mouse at 1/5 price of Evoluent's (I paid $20), so I got one just out of curiosity. Here is quick comparison:Brand - Evoluent VS AnkerPrice - $100 VS $20Build Qaulity - Solid (3 years old) VS Feels solid (only had it for one week, time will tell)Size - offers different sizes VS One size fits all, too small for large hand.Weight - half lb, a heavy mouse (V3) which may require a Teflon mouse pad. VS lightweight.Ergonomically speaking, Evoluent is a superior mouse for the following observations:1. ANGLE: Anker mouse is not completely vertical, so I find myself resting the weight of hand on one spot; the pisiform bone against the tabletop surface. No such problem with Evoluent mouse, because of its form where the hand is resting on top of it.2. FORM: I find myself squeezing Ankler mouse to get a good hold of it, forcing my hand fits into the concave form VS resting my hand on Evoluent mouse, let the form fits into my hand.3. BUTTONS: Anker buttons require a good amount of pressure to click them, that's one of reasons that I have to squeeze Anker mouse to press the buttons. Evoluent's buttons are similar to Logitech's mice, very responsive and don't require much pressure to click.Conclusion: Both mice are a wrist saver compare to conventional mice. Evoluent feels very natural and effortless VS Anker feels a little bit forced, due to its concave form and hard click buttons.Vertical mouse takes sometimes to get used to, but it really works and will save you from carpal tunnel. I think Anker mouse is good for casual use. If you use mouse 8 hours a day, then I'd recommend Evoluent mouse. It's a very expansive mouse, but cheaper than medical bill.

Disappointing

I purchased this mouse because of the Bluetooth capability and the description said that it had a replaceable battery. Unfortunately, the description was for the newer model of this mouse which cost $20 more. The battery is NOT replaceable on this model. It is not even accessible. Had I known this beforehand I would not have purchased either model.The mouse connected via Bluetooth immediately and initially worked flawlessly. On the second day for some unexplained reason the cursor "froze". I was able to navigate using the keyboard cursor keys and therefore reboot which solved that issue. Two days later the cursor disappeared entirely. I connected a wired USB mouse but still had no cursor. I pressed the "Connect" button on the bottom of this mouse several times with no result. I cycled through all three connection choices a couple of times and finally got the cursor again.I am semi-invalid so am limited as to physical activity and therefore spend a lot of time on my computer. Years ago I had another Logitech mouse with a rechargeable mouse which, possibly due to heavy use, needed recharging almost daily. This is why a replaceable battery was an attractive option for me. Although thus far the battery in this mouse has not required daily charging based on the lights indicating the amount of charge it won't go much past that with my usage habits.The "Options" software is unneeded. The keyboard cursor keys are quicker and more positive that the horizontal scroll thumbwheel. The horizontal thumbwheel is too close to the Forward and Back buttons which sometimes results in some unexpected cursor behavior.On several occasions the left mouse button has been unresponsive and on several occasions would not move.I have decided to revert to the wired USB mouse that came with my computer. I have not had satisfactory service from any wireless mouse of any brand.
Meh, pass on this mouse
May 3, 2017
Want to love this mouse like I loved my G5 mouse from Logitech. but I just can't.First; this mouse's software stack is garbage. The UNICODE settings app they install with their package is ALWAYS crashing on Windows 10 64bit. It crashes on many game apps like BF1. Just garbage.Second; the mouse doesn't communicate well with the Logitech receiver. I'm not sure what's going on but this is a fresh Windows 10 install and I'm constantly getting frustrated with "hesitation" of the mouse pointer. IE a minor move of the mouse should result in a movement of my mouse cursor. If I were to guess; the unifying receiver stack must be relying heavily on getting "bandwidth" to do some kind of processing. If I run my CPU at 100% the hesitation/lag is really bad. It's almost like the unifying receiver doesn't use the Interrupt system well enough or there is a power management issue with the mouse / receiver.Third; this mouse is advertised as Bluetooth compatible. It's not. After pairing with my BT enabled desktop (intel WIFI card w/ BT 4.0); it frequently drops the connection and won't re-pair with the computer. Not sure why. As a result; I had to use the unifying receiver.It took me a while to figure out why the mouse was so frustrating that I couldn't return it to Amazon.My advice; is to avoid this mouse.
SHORT battery life often with no warning that it is running down.
March 21, 2017
After two full months of use:PROS: Tracks pretty well on some surfaces, decently comfortable in the hand.CONS: SHORT, UNPREDICTABLE BATTERY LIFE. About a week or less in normal use. If you miss a short warning flash on the screen that the battery is running low, then later with no additional warning the mouse goes dead all of a sudden. Then it's part of a day of dragging around a stiff charging cable on the desktop until charging is complete.Does not track on quite a few surfaces; finicky.The "spin to scroll fast" feature works after a fashion, but it's kind of hard to control how fast and how far it goes. Stopping the spinning with the touch of a finger has kind of a hard mechanical feel to it.Don't get me wrong, this is not a terrible mouse. But the engineering of battery life and tracking on some surfaces leaves a lot to be desired.PLEASE BRING BACK the MX 1100! What a great mouse that was.Logitech: PLEASE do not make mice with a short battery life. Good for the environment to use rechargeable mice, but you must engineer the mouse to last longer AND give adequate prior warning in a persistent fashion so users are not suddenly caught mid-computing with no working mouse.
MX Master is more like MX Jack of all connections but master of none.
March 20, 2017
I was excited to buy this mouse because of the new color. It looks better than the original color. I received the mouse, and I was impressed with its build quality and feel. It connected via Bluetooth with no problems and the first couple of days were great. A week later the mouse started to lose connection and then regained it. I thought it was because it went to sleep after not using it for a while. Then it began to disconnect while in use. I do a lot of design and illustration work. One of the most important things for a designer is to have a tool they can rely on especially on those critical moments when you have to crank the work out to meet deadlines. This mouse is a disappointment.I went online and searched my particular problem and saw I was not the only one with this issue. I even came across a Logitech support forum where the Logitech rep said that the Bluetooth connection is not reliable. He recommended to instead use the dongle provided with the mouse. Okay, first off, a person buys a Bluetooth device to use via Bluetooth. I do not have the patience or the time to babysit a dongle that can be lost easily. I travel too much, and I don't need anything taking up my limited USB connections, and no a hub is not an option. Yet another thing to carry and lose.I use the k811 Bluetooth keyboard. It's brilliant, and I had it for six years with no issues. Why can't Logitech create a Bluetooth mouse that is as reliable like the K811? It just seems a simple thing to do.If you are already a Logitech dongle user, then this mouse will be okay for you, but if you need Bluetooth. Look for another option, because all you will get is disappoint with this mouse. MX Master is more like MX Jack of all connections but master of none.
Fundamentally Flawed
February 24, 2017
There is a common problem with this mouse - the mechanism that allows the mouse wheel to either be in "click" mode, or free-wheeling breaks after a while, leaving the wheel in free mode only - you can technically fix the problem by opening the mouse and re-positioning a little rubber ring that's held in place by friction that slides down rendering the mechanism useless. But it requires removing the mouse slider pads and getting into the internals of the mouse.I have had two of those, and both of them have had the same problem after about 12-18 months.The problem with the free-wheeling mode is that the scroll wheel tends to drift as you move the mouse (it's so sensitive).All in all, I like the size and feel of the mouse, but it basically lasts me one year.Logitech build quality has definitely gone down in recent years (see my review on the their Solar keyboard - flimsy plastic legs keep breaking).
Way overrated...
January 14, 2016
This mouse does seem to live up to most of what people are saying—though it seems this is one of those products people get hyped about and write a review for after 5 seconds of use, so I wanted to contribute something I DIDNT get to read when i was researching the mouse.First of all, its bulky and pretty much forces you to cup it with you entire hand. I'm 5'11 and my hands aren't small... I've used a Razor Deathadder for years and love everything about that mouse, except the crappy construction that almost guarantees it will be double clicking within a year.The size/ergonomics is definitely a subjective complaint, but people seemed to rave about them even in comparison to other slim mice, which is confusing to me after having used it. If you're used to a fingertip grip, high DPI with minimal wrist movement... you'll hate this. The feel of the mouse moving on the screen feels "rubbery". Not sure how else to describe it. Just less accurate and quick than the death adder. I think you're paying a premium for their branding and that crazy promo they made about this mouse.I noticed when i barely tapped the side scroll wheel, the primary scroll wheel stops responding (for a while). This seemed to happen more and more often as I used it. I researched it and apparently its a problem with like .... a LOT of people, and its still unresolved. Based on the forum post I read, which was 9 pages long and multiple years worth of posts, it seems like it may be more than just a driver update. I returned the one i ordered and bought something else.

Doesn't play with Mac, mouse is good though.
August 11, 2017
Initially this worked great. My coworker has one (different brand) and I wanted to try it. First week of use was great, was comfortable and the mouse worked great.However, after that first week I've had nothing but connection issues. I'll turn on my computer or wake it up from sleep and the mouse just won't connect. I end up have to turn off the mouse, unplug the transmitter, wait a few seconds, plug it back in and turn on the mouse again. Rinse and repeat about 5-10 times before the mouse finally connects. Once it is connected it works fine, so not sure what the issue is.I recently upgraded to MacOS Sierra, so I'm guessing it is a driver problem with them.I like the mouse when it connects to my computer.
Updated - Nubbin Didn't Stand Up
July 3, 2017
--Update--After I got used to this mouse, I loved it, but then one day (today), it was suddenly inoperative. I tried new batteries, but no go. Had to hook up an old mouse. I found that the plastic of the bluetooth nub was bent at about a 30 degree angle, which I assume is the culprit. The thing is, it's been in my laptop since I got it, and my laptop is handled pretty gently. I carry it in a laptop bag, and it goes in and out of my trunk daily, but apparently this was enough to bork the nubbin.This makes me really sad because this mouse really did help my shoulder A LOT.-- Original Review --Picked this up to help with my shoulder hurting while sitting at a low desk. Taking the rotation out of my wrist has helped my posture and all nerve pain in my shoulder virtually disappeared.Taking one star off because the smooth texture of this mouse makes it difficult to pick up and move (like ya' do when you're at the edge of the mousepad). My fingers literally slip off of it. Some strategically placed rubber grips would make this a 5 star mouse.But it works great, and helped me out quite a bit. Plus, it turns heads when I haul it into the conference room with me! ;)
Smells bad
May 8, 2017
This mouse looks like a great deal for those who need a vertical mouse, but after using it for an hour, I've returned it.First off, the sensor works well enough and I didn't experience any tracking issues for normal desktop use. The real glaring issue is how stiff the mouse buttons are. Every time you click, your mouse will literally move from where you are pointing since the buttons are on the side. You have to grip the mouse with your thumb and push against the mouse to stop it from moving. All this muscle strain defeats the purpose of an ergonomic mouse. I would've stuck it out and hoped the tension on the buttons would decrease with use, but there's an even bigger problem with this mouse.The worst part is that the plastic on this mouse smells like burning plastic AND the smell will transfer to your hand. I returned the mouse because I don't want to risk breathing in the plastic off-gassing or absorbing it through sweaty palms. I had high hopes for this mouse but it's not very usable and the plastic might even be a health hazard.Edit: Big thumbs up to Anker for their customer service. They saw this review and sent me a newer version of this mouse (https://www.amazon.com/dp/B018LR04B8/ref=psdc_11036491_t2_B00BIFNTMC). The mouse buttons are much softer so it eliminates the problem of mouse movement when you click, but the plastic still smells horribly. I've let it air out for about a week and it doesn't noticeably smell anymore unless you hold it close to your nose. It doesn't transfer to my hand, which is the most important part. The side mouse buttons (mouse4/mouse5) aren't the easiest to click, but it's acceptable enough that I'm willing to overlook that problem. I'd give this mouse a 4/5 overall.
Not perfect but a solid alternative to the pricier models
May 8, 2017
Bought this mouse because it was worth the $19.99 risk compared to more expensive models, and it definitely proved to be worth the money. The ergonomics of this mouse are far better than any other mouse I've used, and have relieved tingling and pain in my thumb and fingers from a trackpad. The ONLY issue I ever have with this mouse is that sometimes it's not smooth (the mouse movement), as in the mouse on the screen is jittery as it moves where you tell it to move. I cannot guarantee that it's the mouse, but I suspect that it is. The setup I personally run is the mouse with no trackpad on a flat white desk with the bluetooth receiver plugged into a USB hub that is plugged into a laptop. 95% of the time the mouse works perfectly, I only have issues with the smoothness every so often.Update - After a little while of use, the track wheel on the mouse became unusable. I can't scroll up or down pages. The page moves but then returns to the original place. It doesn't seem like a physical issue as the wheel moves smoothly but maybe a lower-level issue. Will be reaching out to customer service soon to get this fixed.
AVOID! Doesn't Track, Buttons don't Register.
September 4, 2015
Bought, used for a week, returned it. The angle is definitely interesting, but can get used to it after a little while. However, the big issue I had was the tracking/buttons.EXTREMELY FRUSTRATING! It constantly skipped, and wouldn't track the mouse movements. Meaning, I'd move the mouse, and it wouldn't track. I'd have to rapidly shake my hand back/forth to get it to register the movement. I'm using a brand new, black, high end mousepad, but I tried it on other mousepads and surfaces- same issue. It also had issues with the buttons not detecting a click. Many, MANY times I'd have to click, and it wouldn't register- so I'd have to click multiple times, and forcefully hold the button down to keep it engaged (for highlighting or dragging the cursor).Also- I found it very annoying that it'd turn off after a few minutes, and I'd have to click the buttons to get it to turn back on every time. I know there's probably a setting in there to change that (and it saves battery life)- but with the other issues I've been having I was just over it.While the design may be cool, and ergonomics are a step up- this thing is a piece of junk. I went back to a tried and true Logitech.
Hand doesn't feel relaxed.
March 17, 2015
It glides smooth across the desk and my wrist feels comfortable without having to use a cushion or a mat. The battery is great, and I like the sleep feature it has.However, my hand doesn't get to relax. The smooth surface of the mouse makes your fingers feel like they are slipping and it's also feels like you have to keep a grip on it. I do a lot of design work and I don't think it's good for that.I would only recommend this to someone who doesn't have to use thier most that much.It was nice at first but now I don't like it that much

Best to look elsewhere.
November 13, 2017
The mouse works great, but Logitech's lousy customer service sours the product. Best to look at companies who actually stand by their products, instead of sending you into a black hole. There are only two possibilities with their lack of customer service. 1. They don't care. 2. they have so many complains in queue that they can't work trough the mountains of repair requests. My recommendation is to choose wisely and look at something different. Unless of course you live for the moments where you get to submit a warranty request, just to see how many months or years it takes to get an answer. If you buy this mouse, it may be wise to submit a warranty request the day you get it. By the time Logitech gets back with you it'll be about when the mouse breaks a few months from now.
No good for 2017 iMac
September 10, 2017
NO GOOD for 2017 iMac 27"No good for 2017 iMac 27"!!!! Not only does this mouse skip and randomly jump all over the place, it also gets stuck on right mouse button regularly? That means when your clicking the left button, it thinks your clicking the right!. Check the forums on this and it will verify what I'm saying. Even Logitech admits there's an issue using this with a Mac. I even disabled the bluetooth and used Logitech's USB Unifying Receiver. It did not help.Here's the response directly from Logitech:"Dear Users,We are aware that some people are experiencing issues when connecting their peripherals to a Mac using Bluetooth Smart technology. These issues are related to the way the Mac OS interacts with Bluetooth Smart, a technology that is included in a wide range of products. We are working directly with all parties involved with the issue -- Apple, chip manufacturers, and the BTLE industry board -- to help find a resolution.If you use a Mac and are experiencing these issues, we suggest using the Unifying Receiver included with your MX Master to ensure stable connectivity.We will continue working with all parties to ensure full resolution of connectivity issues.and will share updates on solutions for this issue as soon as we have them. In the meantime, thanks for your patience as we work to solve this problem."SO BASICALLY THIS MOUSE IS NOT COMPATIBLE WITH A MAC!!!!!
Like Pushing A Shopping Cart Through a Closet
April 27, 2017
This mouse is a "full-size" mouse. I guess the original mice made by Xerox, Apple, & Microsoft were, well, micro. At least according to Logitech they are. What Logitech means by "full-size" is BIG. They're using the term euphemistically. Kinda like a "cozy" house meaning "small," and a "plus-size" model being, well, big. It is so big my keyboard & mouse sliding tray wouldn't close with the mouse on the pad.That thumb-rest to the left is just plain stupid. It always gets in the way, cutting down on your mouse-pad real-estate by 25%. Buy a regular sized mouse, cut 2-inches off the top & left of your mouse-pad, and you'll get the same effect. I don't know who's dragging their thumb-knuckle like a Neanderthal that requires this bulky profusion, but whomever, it's just a stupid idea put into product engineering. I have two Logitech mice with this thumb-rest, and many Logitech mice that don't have it. Trust me, it just gets in the way.Logitech brags about how they sanded down a block of wood to get *just* the right size and layout for the mouse. If this is the best they can do with carving wood, color me unimpressed. A 7th-grader could crank out a design like this in an hour if he knows where the sanding block, sandpaper, & saw are.. The button layout is nothing special. No ergonomic miracle here. While not terrible, they aren't special or noteworthy either. $100 retail for bad-engineering & $3 worth of parts, shipping, & warehousing. I think this mouse made me fall in love with my M705 all over again.Lastly, it's just plain ugly. It is SO 1990's. The colors are weird, the embossed diamond-pattern is as anachronistic as it is pointless.
Major problems with ergonomics and bluetooth lag; just go with the M500 or similar
April 7, 2017
Cons (very, very many):1) It's too high - just an unnatural hand position that makes the hand tired.2) The weight is shifted too far to the front, meaning that you need to use more of your fingers to move the mouse rather than using more of your arm.3) Way too much friction on the bottom side of the mouse, although this is easily solved by replacing the pads underneath with Hyperglide Mouse Skates.4) The mousewheel wiggles around, such that when you start moving the mouse in a new direction, you feel a jerk inside. Not very smooth.5) Experienced lots of lags/jitteriness due to the Bluetooth connection, even though I used the included Logitech dongle.Pros:1) The horizontal scroll (the second scrollwheel, by the thumb) is a "nice to have", although doesn't add a whole lot of value since you can usually scroll horizontally by pressing shift or ctrl on the keyboard - which is usually easier anyway.2) The laser works on glass, which is probably a "nice to have" for 1% of the population.I tried about 6 different mice after very detailed research and ended up sticking with the M500 wired mouse ($25), with Hyperglide Mouse Skates (to fix the friction problem that apparently exists on all Logitech mice). M500 feels way better.
Cursor stopped moving, buttons still work.
March 2, 2017
Update: A few hours after un-pairing/re-pairing to get the cursor moving again, it stopped working yet again. Now, no amount of un-pairing/re-pairing will get it to move. This mouse is a dud.Update: After exactly a month, the cursor stopped moving occasionally but the buttons still worked. If I fiddled with it, turning it off and on, switching the connection, it would come back, but now it has stopped completely. Doing a quick search, it seems that this issue comes up quite often with Logitech mice. By unpairing the device and repairing through the Unify software, the cursor started moving again, but this shouldn't have to be the case. I haven't had an issue like this before with other mice so YMMV.Great mouse, loves that it has both BT and wireless transmitter with three pairs for multiple computer use. The only part I do not like is the auto-infinity scrolling. It's too easy to accidentally trigger the infinity-scroll when all you intended was a bigger than normal racheted scroll. While Ctrl-Tabbing through Chrome tabs, I accidentally held the Ctrl button to long while scrolling and it zoomed to 500%. It has a button for switching between infinity scroll and racheting scroll. I wish it would honor what I set it too.
Scroll wheel defective
March 26, 2016
I bought the MX Master because I have had two MX Performance mice that I love. They are comfortable and the battery lasts for a couple of weeks. The MX Master is supposedly an upgrade from the MX Performance, and I was pretty pleased with it yesterday when I took it out of the box and started working with it. One neat feature is the scroll wheel that automatically changes from "ratchet" to free spin...until it doesn't. As of this morning the ratchet mode no longer works, and the Logitech forums were full of reports of the same issue. I verified all the settings, turned the mouse off and on, tried it on another computer...all to no avail. The scroll wheel appears to be broken. I have returned the mouse and am looking for a replacement.

WASTE of money and DOES NOT FUNCTION PROPERLY! *** AVOID***
September 7, 2017
in some applications the buttons do not function properly, such as Chrome and trying to grab the side scrollbar, using the left mouse button, and scroll up or down or in VLC to select menu options on menu bar with the left button, maybe its my unit and the left button, but many times in various applications, it just doesn't work as it supposed to. I would honestly tell you this was a waste of money, it DOES NOT function properly and is more of a headache than a useful mouse. I DO NOT RECOMMEND and would honestly tell you to avoid it!! - I am running an Intel i5 -3330 with 6GB RAM on Windows 8.1 with all updates. Cannot make it work properly or find a solution. DON'T BUY THIS
Increases pain, not good for smaller hands
August 7, 2017
I bought this hoping it would alleviate my cubital tunnel syndrome (ulnar nerve) but it actually makes the pain worse. It takes a lot of force to click so it puts more stress on my wrist and arm. Also, while my hands aren't particularly small for a woman, I can't reach the scroll button. Also, the cursor randomly disappears and I have to turn the mouse off then back on to wake it up.
This mouse is good when it works
January 31, 2017
This mouse is good when it works. It takes a couple of weeks to get used to in your palm, but once I got used to it my hand felt better and it dramatically decreased the paid I used to feel when clicking and moving the mouse. However, the first one died in exactly one week fortunately I contacted Anker and they sent me a replacement, the second one has just died after only a couple of months. I never dropped them or spilled any liquid in them, they just die mysteriously. I tried to replace the battery, no luck. They should make them more reliable not just make something that dies after a few uses.
causes my wrist to rest uncomfortably on the bone.
January 4, 2017
Not sure yet whether this is an improvement over normal mouse. Wanted to point out that it causes discomfort on the wrist bone nub that is directly in line with the pinky. imagine you are shaking hands and then put your hand down on a desk in that position--with your wrist essentially 90 degrees rotated from the "normal" position for a mouse. with a normal mouse my wrist would rest on the middle soft part. i'm trying with wrist pads etc to see if this will work, but wanted to point out that this might be a concern.Updating my review. Less than a year old and it is now eating up batteries, which have to be changed every 2 weeks or so. Today the scroll button just stopped working. Starting to rethink the Anker brand.
I liked it because it did help with my wrist hurting ...
August 30, 2016
I liked it because it did help with my wrist hurting but it keeps having all these issues. The pointer will just disappear from my screen. For some reason does this continuous scroll that I can't stop and it freezes some of the applications when I click on things. I thought it was my computer but after really looking into it, it was just the mouse. I have only had it for a little over a month and I have to switch back to my mouse. Good concept but spend the $$ to get a better one.
too bad, I really like the design
September 7, 2015
Before buying this vertical mouse, ask yourself : HOW BIG IS YOUR HAND ?with traditional mouse, size doesn't matter *that* much, as your hand rest horizontally on it. but with Vertical mouse, if it's too big (by big, I mean, too tall), when i put my index finger on the left-click button, the right side of my palm was NOT on resting on the table. As a result, it cause pain on my wrist -- just fyi, I have small hands, length from tip of middle finger to end of the palm is a little over 6 inch.Have to give it to someone else with bigger hand, too bad, I really like the design.
