Side by Side Comparison of: LuguLake vs Anker vs J-Tech Digital vs Summit Merc. vs SHARKK

Just received my second one of these and I am very happy with it. The first one was purchased used and even so it lasted me a year of 10-15 hours a day of off and on use (yeah, I know, there's a big world out there) until the scroll wheel died. I think that's a great value. I'm looking forward to a longer time with this new one. It's very comfortable for me with severe arthritis in my thumb, even more comfortable than the Wow Pen Joy, which is a fine product but which is smaller. The size of this works well for me as I have large hands.

I need a vertical mouse in an attempt to relieve the discomfort due to my carpal tunnel syndrome. It took me about a day or two to get used to the new position of using a mouse. I didn't feel any effect immediately and was not sure how much this mouse will help to release the tension of my wrist or how long it will take. However, I decided to keep using it. After using this mouse for almost 5 months and applying some physical therapy, my wrist felt a lot better and can function quite well again. I'm very happy with this product.

This arrived today and I've only been using it for about an hour. I will update this review if anything goes wrong, but so far, I really like this mouse. I bought it to replace the Anker mouse, which I've had for about two years. The Anker was still working, but I wasn't happy with it anymore. The buttons were not as responsive as this LuguLake mouse. I right-click a lot and I found that the Anker was taking several tries before it would work properly. I've read that this is an issue with the Anker right out of the box. It seemed to get progressively worse over the last few months. The LuguLake mouse buttons are very responsive and so easy to use. It is more vertical than the Anker, which I like. I feel like using the Anker for a long time has prepared me for using an even more vertical mouse like this one. You also can't beat the price of this. I almost bought the really expensive Evoluent mouse instead of this, but now I am glad I didn't.

I used an Evoluent mouse for yrs w/my Mac. I had a lot of issues! One, it conflicted with Perfect Photo Suite. Two, it wouldn't recognize drop down menus in WordPress sites. Considering I create and use tons of WP sites, that's a problem. There were other issues which that drove me nuts. But those 2 killed it for me. I just got this mouse. It works. If it falls apart in 6 months, that's fine. I'll buy 2. I can buy a lot for what I'd pay for Evoluent.

So comfy! the black material feels very good to the touch. My poor hand has been hurting since I stopped using the Evoluent. Scroll button is awesome! Very comfortable, great touch. I've been using Macs and PCs since 1987. I've used a lot of ergonomic mice. I wish this company had some good PR cos they are onto something here. Raves raves.

PS I rarely leave reviews. I feel so strongly about this mouse I'm going to blog about it. Finally a product I can rave about which works and is affordable. Such a deal!

I have tried 4 different vertical mice thus far (Evoluent, 3M, Anker, and Lugulake) and this is the one I am using and will re-order should I ever need another one. All the other vertical mice are much more expensive- from 50% more cost to nearly 9x the cost! They all have their different virtues and shortcomings but overall this one is the winner in my opinion. I will be specific here- I like the hand position on the Anker the best, but its clicking mechanism is its downfall. The Evoluent is clearly top of the line in every regard but I prefer the lower hand position of the Lugulake which makes it easier for me to be precise. The 3M mouse is nicely done but using my thumb to click all the time stresses it from the unusual movement required. Additionally, trying to scroll with the 3M mouse leaves much to be desired. Even if you take away the price factor, I would still use the Lugulake mouse. Give it a try.

I started working from home on the computer all day for work. I started having some wrist pain and tried this to see if it helped. Shortly after using it the pain had gone away. After using it several months the bottom/side of my wrist started to hurt a little from resting on it. I started using a mouse pad and that fixed that. Some people have complained about the scroll wheel breaking. I think it takes some time to get use to pushing it to the side instead of down. Pushing down could break it. I caught myself trying to push down and after some time using it I have gotten use to pushing it to the side. I recommend trying one if you are having pain from using a mouse a lot.

I bought this after reading a review that said once you get used to it, it's a good mouse. I didn't have to get used to it at all. It felt perfectly normal immediately. I'm not sure I ever want to go back to a horizontal mouse again.

It's an amazing mouse for the price. I replaced a more expensive mouse with this one, and I'm happier with this one. I hope it holds up over time, because I love it.

One of the best things about this mouse is where the extra buttons are located. So many mice I've tried put the buttons so close to my thumb that I'm constantly clicking them by accident. The extra buttons on this mouse are in the perfect location so that I only click them when I mean to click them.

If there's any con at all, it's that it's a bit big for my hand, but not so big that I'm uncomfortable with it.

After writing my initial review, I feel compelled on my own to write a more detailed review.

I have used various Anker products and I have always been impressed by their beautiful industrial design, quality workmanship, and high usability and functionality. This mouse was no exception.

The 45 degree position of the mouse makes is really comfortable and ergonomic to hold, compared to other vertical mice that I have tried, which tend to be 90 degrees and too vertical.

In addition, the surface of the mouse is in a very comfortable type of material, which seems unique among the mice that I have tried. This speaks volume lot of Anker's attention to detail.

For me, I still have not fully gotten used to clicking with my wrist in a vertical position. I just read one of the reviews which suggested that I need to squeeze with my thumb and index finger, so I will give that method a try in the future.

I have recommended this mouse to others, and most of them have found it extremely comfortable. I am giving this to a friend who has been eyeing this since I got it.

In addition, I read that the newer version has a bit less vertical, still vertical enough to be very comfortable, but perhaps it will help my fingers transition to vertical mouse position.

By the way, after posting my initial review, Anker's customer service e-mailed me within 24 hours and offered me to try the newer version! I am really surprised and truly impressed by their follow up and offer. With over 1100 reviews, and a 4.3 star rating for this mouse, Anker didn't have to follow up with me, much less to make me such an offer.

With amazing customer service like this, they have earned a loyal customer in me!

Original review:

Very comfortable. However, I find clicking the button with the index finger is a bit hard for me when my wrist is in this position. So I stopped using it.

LOVE this mouse. I bought it because two weeks into a new job that required a lot of mousing, using a normal-shaped mouse was causing me lots of wrist pain. I have permanent nerve damage in my other (left) wrist, and I wasn't about to let the same happen to my right hand/arm. As soon as I started using this Anker mouse, the pain went away. I've been using it for over eight months now and love it. I've had no problems whatsoever with it. It will take some getting used to since the shape is different, but it's totally worth it.

This is the second ergo mouse I've purchased from Anker. I purchased this exact version several years ago and it held up very well. I don't expect these things to last forever and when the old one got worn out, I wanted to replace it with a duplicate.

Excellent ergo mouse, very comfortable, accuracy seems great and the soft-touch plastics are a nice choice.

"love it" is strong wording for a mouse, but it's really really good and I'm happy to be a repeat customer.

I went looking for a vertical mouse after experiencing increasingly severe wrist/shoulder/neck pain from computer work. I picked up this one along with a similar one from Anker, since I wasn't sure what shape would work better for me. The J-Tech ended up being the clear winner for me and is now my daily driver at work. The Anker one is now at home, since it's still better than a regular mouse; but I like it less than the J-Tech on just about every level. The Anker's buttons feel harder to press (putting more stress on my hand and wrist), and their locations feel less natural to me compared to the J-Tech (especially the back/forward buttons). The scroll wheel on the J-Tech feels better and more responsive, and the design puts my wrist in a more neutral position than the Anker. The dpi button is easy to access but hard to hit accidentally. I don’t know if I looove the ridged surface of the rubbery bits, but it doesn’t actively bother me and I mostly don’t notice it.

I did follow the tips here to remove the weights inside the mouse, but I’ve kept the little wrist pad attached since I’ve found it to be more comfortable for me. My wrist and shoulder pain hasn’t completely gone away, but it’s much improved, and I immediately notice the difference if I have to use a regular mouse for any period. Also, don't be discouraged if for the first day or two, you feel like you can't do anything with this mouse! It definitely took me a few (frustrating and slow!) days to get used to it, but then after that it's no problem.

I would definitely purchase this again, and may end up getting a second one to replace the Anker at home anyway.

This mouse is amazing.

I had been having some carpal tunnel issues for several years; I work about 11 hours a day in front of the computer, then go home and relax on the computer every evening. I spend the majority of my waking hours staring at a screen, mouse in hand. Accordingly, I started to develop some serious problems using my mouse after a few hours every day. It started off as a minor pain, but eventually it became a persistent pain. Something had to change.

I found out that Vertical Mice could alleviate the problem; I was skeptical -- VERY skeptical -- but I decided to give it a try. I ordered the Wired version of the mouse, since it was the cheaper one.

The day I recieved it, after using it for about two hours, I immediately ordered two more; One for the office, one for my wife. This time, I chose the wireless ones. I absolutely love it.

Without changing anything but my mouse, my carpal tunnel pain is COMPLETELY GONE. The graphics showing your two forearm bones twisting with traditional mouse use are accurate; Vertical mouse use prevents this problem and I'm not sure I can ever go back. I decided to leave a review after my brother-in-law that lives with me asked me to order him one as well.

This mouse is cheap, but well built. We don't use the removable palm rest, although it was one of the reasons I chose this model; I've found I'm slightly more accurate and have to move the mouse even less when I don't have the rest on. The scrolling is precise, the two thumb buttons are placed with enough space to rest your thumb in between them without hitting them, and the two main mouse buttons have a really nice springy action towards the tips of the buttons that's somewhat hard to describe.

If you have RSI or carpal tunnel, GET THIS MOUSE OR THE WIRELESS VERSION; It will change your life!

I have been used to working with ergonomic peripherals at my workplace and wanted to get one for my home system as well. But at the same time, I was not looking to spend a lot of money. Going by all the reviews posted, I ordered this mouse to give it a try.
The mouse arrived well in time and in a nice packaging. As per one of the reviews listed, it was claimed to be a heavy mouse but I did not felt that it was heavy. In fact it just appears to be the correct weight while using. Especially when compared to the other ergonomic mice that I have been using, this one seemed to be having the the correct weight, if not the perfect one.
Coming to the usage, the most important aspect, I have been using it for almost a week now and am happy with the performance. While it does what it is supposed to do - being an ergonomic mouse, it definitely has a learning curve to it. But once I got used to it, it is really comfortable to use, even with prolonged sittings.
The mouse runs on two AAA batteries - a pair comes with the mouse within the packaging - a really nice thing to allow you to get going immediately. The mouse gets detected immediately when plugged in, no specialized drivers or installations required.
Overall I am really satisfied with the purchase and would definitely recommend this mouse, if you are looking for one on budget.

As a software developer, I am semi-permanently attached to a mouse and keyboard. After more than twenty years in the industry, my wrists and digits have taken the brunt of the storm. Until recently, the worst of my work-related pains has been on my thumb from the way it rests on most mice. It locked and popped non-stop, and was miserable by the end of the day.

The reason that most of that is in past tense is due to this mouse. After trying numerous ergonomic mice and other pointing devices, I decided to try a vertical mouse. My searches landed me on this product, and the reviews were encouraging. It was packaged as would be expected, and I was up and running with the mouse in a matter of minutes. However, you do have to learn to walk before you can run. There is a learning curve, which comes as no surprise. It is just so very different than a traditional mouse, that you will find yourself wanting to hold it in awkward positions.

After a few days, though, it starts to become more natural. Three weeks in, and I could not be happier. While it does take some getting used to, I can honestly say that the pain in my thumb has been reduced by at least 75%. So, I have bought a second one for my mobile workstation, and my wife's interest is piqued to the point that I imagine that I will be ordering another one soon.

I have a history of elbow/wrist/hand pain in my mousing arm from a career of pointing and clicking on things. At work they prescribed me an Evoluent Vertical mouse which helped considerably. I bought this for home usage when I realised I was leaning to the left at home to try to simulate the same vertical mouse feeling on my home computer. If you haven't tried a vertical mouse you should, even before you start feeling pain. The over-pronated wrist position of normal mice crosses your radius and ulna which compresses all kinds of internal structures and it's not good for you in the long run. Using a vertical mouse takes a few days to get used to but it's worth it. As an added bonus, it used to annoy any of my colleagues who tried hi-jacking my ergo-mouse/keyboard to show me something at my desk... After a few clumsy attempts to click on things they'd always give up and return it to me ASAP.

So far I like it a lot. I also tried the Sharkk/Adesso vertical mouse at a shop. I like all four mice but so far I like this one the most. I have the wired version for my desktop.

Texture: My Evoluent mouse had a shiny slick texture that never felt that good in the hand and would collect a lot of fingerprint gunkage. This had a matte rubbery feeling surface with grip ridges. The Sharkk/Adesso mouse looked identical but the Adesso had the shiny smooth surface and the Sharkk was matte. I preferred the Sharkk to the Adesso FWIW.

Shape: This mouse has a more naturally curved hand shape that feels very natural in my hand. The Evoluent mouse was a simpler lump of rounded plastic. It's a better orientation than a regular mouse but it's not a great shape. I also like the wrist guard on this one - with my evoluent mouse, my palm heel always drags and get sore after a while.

Buttons: The buttons on this one feel much more solid and better placed under *my* fingers than any of the other three I've tried. The evoluent buttons always seemed too big and too long for my hands which meant harder actuation. The Sharkk/Adesso ones seemed OK but were more like long leaf style buttons than actual buttons and lacked feel. Some people have complained about the positioning of the thumb buttons on the J-Tech - I haven't had any trouble with them thus far but I remapped them with xmouse (no drivers are included). I guess you could disable them if they annoyed you. The thumb buttons on the Evoluent mouse are quite far apart - so far apart I never used them. The DPI button is large and better placed than the DPI button on the Evoluent mouse (under the palm?). Unlike the Evoluent mouse however, it doesn't have an up/down DPI button and it does it silently - it doesn't have LED indicators to tell what speed it's on. It just does it.

Size: The Evoluent mouse might work better for bigger hands - I believe they have wider range of sizes and left-handed models. I'm 5'6" and male FWIW. The J-Tech mouse works well for me but I can imagine someone with bigger hands finding it too small. I'm considering the Sharkk/Adesso mouse for my laptop since it seems a little more compact than either of the other two options.

Overall the J-Tech mouse is my favorite vertical mouse of the four I've tried, at least in the hand. I haven't tried the Adesso/Sharkk mice but I'd be willing to try them for mobile work, sacrificing the wrist guard and better shape for more portability. I'm not a fan of the Evoluent mouse at all any more. It's better than a normal mouse but it doesn't seem worth the extra money on ergonomics or longevity (I'm on my second: one burned out in under a year). Lefties and giant ham hands might need to check them out though.

my mom bought this for me as i lost my right hand due to a sickness and i am now forced to be left handed and i honestly couldnt believe how hard it was to use the internet until we found this mouse!!! Its so comfy to rest your hand on and the cord is actually a plus, now i can surf the web and play my games again

Amazing Left Handed Mouse. Wife Loves it and got used to it super fast.

Bought as a gift for my grand mother and she loves it and it works like a charm!

Perfect.

Finally an affordable left handed, corded mouse. Works Great!

Bought this mouse for my wife and she positively loves it, great product and wonderfully fast shipping.

Bought this for a senior neighbor. The side ways orientation takes a moment to get used to and it does put the side of your hand in more contact with the desk surface. So it works great for things like touching up pictures that won't require a lot of motion but not as good if you need to point all over a large screen or multiple screens.

I started using this mouse at home and at work about eight months ago. The ~45-deg angle relieves the strain on my wrist, so that's good. The buttons and the wheel have worked fine on both.

However, the cable of the mouse used with the desktop computer had some tension on it periodically for a few months at the end of the eight months of use, because the cable was getting caught up on other cables behind the monitor, so we had to pull on the mouse to get some slack when that happened. I don't mind the cable and like not having to replace batteries. (Batteries can fail at awkward times.) This pulling went on for a couple months, then the mouse started working sporadically. I changed the cable layout behind the desk, so the mouse cable didn't get caught anymore, but too late. As I learned from taking the mouse apart to fix it, the cable insertion into the mouse places the cable at a right angle and the pulling apparently put strain on the cable itself (repeatedly enforcing the sharp, 90-deg bend). The cable contains four small, multi-filament wires and tugging on the cable with that right angle apparently broke enough filaments, because once open, I could investigate the connections better. The right angle catchment is to prevent strain on the circuit-board connection, but strains the cable itself. My repair included looping the cable in a "knot" before re-soldering. It's not tight and a continuous curve, so shouldn't strain the cable this way. The mouse is working normally again.

I purchased the Anker mouse and the LUGULAKE Vertical Ergonomic Mouse, so I could compare the two and return the worth one. OK, the Anker® CE100 Ergonomic Optical USB Wired Vertical mouse looks cool, but besides this mine had some flaws: often, when I clicked the cursor didn't stay on an object, but moved. So, for example: when I needed to close a window I wasn't able to do that right away because cursor moved away from the X icon.
This is just an example, but this behavior illustrates inaccuracy of the mouse.
Besides, my hand became kind of sweaty while using this mouse.
The LUGULAKE Vertical feels much more comfortable to work with and is accurate, even though isn't looking that cool, as Anker mouse to me. Above mentioned are the reasons I have returned the Anker mouse and kept the LUGULAKE Vertical.

UPDATE: 04/02/15
The scroll wheel squeals and resists movement now. Seems like downward pressure over time affects the scroll wheel. I have to apply upwards pressure if I want the scroll wheel to move freely and without noise. I believe this to be a design or quality issue as it is happening on both the mice I bought. This is my only complaint so far. Customer support is outstanding but I would rather not have to contact them every 8 months to get a replacement. Taking review down to 4 stars because of this.
UPDATE: 08/26/14 (Original Review below)
Shortly after writing the review below LugaLake customer support emailed me. They offered to replace my broken mouse no hassle. They also confirmed that the cord had been improved and the replacement mouse would feature the cord displayed online. I received a replacement without any hassle just like they promised. I was disappointed to find that the cord on the replacement mouse was the same as the one that had broken. Additionally, I ordered a second mouse for the office and it too had the old cord design. I emailed them and they promptly apologized letting me know they had some old stock. They suggested I keep the warranty replacement and return the second mouse I purchased for the office. My wrist pain is gone with this mouse. Given the low price for this mouse compared to the next best alternative I am going to keep them and see how the cord fares. You can't beat the price and if I get a full year out of it I will be OK. I am giving it FIVE stars because the mouse is GREAT and you can't get anything close for the price. It would be nice if they had taken the old inventory back and replaced the cords but I am sure this would have driven up the cost significantly.

* * * ORIGINAL REVIEW * * *
I have owned this mouse for 11 months. The only problem I have with it is that the cord on the model I own is very cheap. Consequently, the mouse works intermittently due to a bad cord/connection. The picture on the new model seems to show a fabric type cord. If this is true, it may be a huge improvement over the cheap plastic cord on the model I have.

I suffer from wrist and hand pain from prolonged use. This mouse enables me to work an entire day with minimal discomfort.

This is the only time in my 30+ years using a mouse that I have a cord go bad on me so I was disappointed. I have owned mouse ranging in price from $100 to $5 and I have never had a cord go bad on me before. Given the price I can't complain much.

PROS:
[] Great vertical mouse. Works just as well as the more expensive brand at a fraction of the cost.
[] Good solid feel (Except for the cord)
[] Good weight
[] Buttons are firm enough to avoid accidental clicks yet light enough for long use
[] Great price

CONS:
[] Cord on my original mouse is made of cheap plastic. The cord/connector broke in less than a year.
[] Warranty is for one year but their policy requires that you pay shipping both ways, and repairs take about TWO months. Given he cost of a new mouse on Amazon this makes this a disposable mouse in my book and not worth the cost of shipping both ways.

SUMMARY:
Great vertical mouse for the price. I only wish the cord/connector was of higher quality. I am hoping that this second mouse has a better cord. The pictures for the product seem to show a fiber mesh cord, a welcomed improvement if it turns out to be true.

I am giving this mouse 4 Start because the cord broke in less than a year and the terms of warranty make it impractical to send back for repair. Functionality wise this mouse is Five Stars.

I am a mechanical engineer, and I use CAD pretty much 8 hours a day. My "regular" mouse started giving me some forearm pain at the end of the day, so I thought I'd give vertical mice a try. I googled them, and initially found the evoluent version, but I didn't want to drop that much money on something I wasn't sure would work. I then found a couple of less expensive versions, and finally picked up an Anker vertical mouse. I was less than impressed with that one and gave it to my brother after a day or two. It just felt cheap, and the buttons were so hard to push I didn't feel any relief. Recently my cheapo work mouse was annoying me with its non-clicking buttons, I decided to buy my own work mouse, and found this one by Lugulake. It seemed to have generally great reviews, and was cheaper than the Anker, so I figured why not.

Opening the box, (I love reading these types of boxes, with not quite english translations, super funny stuff!) I was pleasantly surprised by the feel of this pretty inexpensive mouse. It just feels more solid than the Anker, with a nice texture and design. Also, the buttons' effort is similar to other mice, and are not something you have to consciously "press harder" to get to work, like I felt like I had to with the Anker. Not as quiet as my Logitech at home, but not as loud as the Anker either. Should be fine in the noisier work environment. Scroll wheel feels nice, but I'd prefer it to be a little curved instead of flat, but that's just nitpicky. All in all a great mouse for $10 bucks. I think if they created a mouse that was a little more expensive, I'm thinking $20ish, with slightly better button actuators (and apparently better scrollwheels, from the many comments about broken ones), people would start saying "What a good mouse" instead of "What a good cheap mouse." I will be taking it to work today and will update soon on if the "vertical" feature is worth the while as well.

So far I have only used this mouse a couple of days but it is more comfortable than a standard mouse to me. However (tl;dr), the buttons are hard to press and the dpi button gets in the way. I also wish they made a left handed version.

My biggest complaint are that the buttons are too hard to press. Especially the mmb. I have to click this and hold it down all day long when working in 3d and I am afraid it's going to cause hand pain issues eventually. Same goes for the other buttons but to a slightly lesser extent. I would pay more for a mouse that had nicer/lighter buttons that only require light fingertip force. I probably only need like 40-45g of actuation force
(going off of my mechanical keyboard).

Next issue is I keep accidentally hitting the dpi button. Honestly I don't even want a dpi button, but I especially don't want one that my thumb accidentally hits because I like to rest my thumb on that ledge

Also I wish they made a left handed version of this mouse because then I would buy one for each hand and alternate. I already do this with a regular ambidextrous mouse.

I wanted to try out a vertical mouse. This one feels solid and conforms nicely to the natural shape of my arm at rest. However, actually using it for work purposes (which is pretty intense use for many hours a day) has been a problem, because I tend to squeeze my fingers around the vertical mouse, and it has caused some cramping in the middle of my hand. It's worth trying out to see if this style of mouse works better for you.

I've used the mouse for over a week and so far so good. It takes getting used to, because you use a different set of muscles to move the mouse, but the strain and pain of using a non-ergonomic mouse is gone. The only thing keeping it from being five stars is that the new hand position feels slightly awkward. If it allowed your hand to curl just a bit more, it would be in an anatomically neutral position. As it is now, the fingers are slightly extended, which puts a small amount of pressure when clicking the buttons, but far less than that of a normal mouse.

This mouse has been great for eliminating my wrist and shoulder pain. I was able to get about 6 months out of it before I started experiencing issues with the scroll wheel, where the scrolling would jump around, or briefly scroll in the wrong direction. I contacted Anker and explained my issue and they offered a refund or a replacement without the hassle of having to return the old one. The new one I received is perfect, no scrolling issues at all! This is a great vertical mouse, especially for the price.

The mouse fits my hand well and is certainly an improvement over a traditional mouse design. Here are my PROS and CONS.

PROS:
- The design fits my hand perfectly and really helps my wrist stay in a comfortable position during an entire work day.
- The buttons have a very satisfying click and are easy to press, which also reduces strain.
- Works immediately with Mac OS 10.11.
- Incredibly inexpensive for an ergonomic product.

CONS:
- The surface of the mouse is rather slick and I wish there was some thumb support. A minor gripe really and I'll probably add some with Sugru.
- There is no visible change on the mouse as to what DPI setting you are using. The red light on the side stays the same. You'll have to remember to change the DPI each time or adjust your OS's sensitivity according to the default mouse DPI setting.
- Not really a con but I do wish that the cord was braided nylon. I know I could get the wireless version but cords don't bother me.

Overall, I'm very satisfied with this product and will be buying another for my home computer as well.

I've been using this wired mouse for about a week now. After having aches and pains while at work in my hand and arm prior to purchasing this, I can honestly say these symptoms disappeared after a day or two of using this mouse.

I have a small hand and while I do wish this was slightly smaller, overall, I'm very pleased with the way it works. I like the way my hand doesn't have to twist to rest on it and it has a soft rubber grip area where the side of your hand rests on it while using it. This rest is removable, too, but I don't know why you'd want to remove it.

My only complaint is that while the rubber grip has ribs on it, it is still a bit too slippery at times and my hand slides down if I'm not paying attention. I don't have sweaty hands and have dry skin, so that probably doesn't help, either. It's not too much of an annoyance, but i do wish the rubber wasn't so smooth.

Other than that I'd say this product is high quality and I've already recommended it to my son and he purchased one last week for himself as he's a computer programmer and works on the computer for up to 12 hours a day. Also, you really can't beat the price as some of the vertical mouse products are upwards of $50.

Obviously these kinds of mice is always a compromise, however after trying several similar devices this one worked the best for wrist pain, just wished it was little larger.I definitely recommend this to everyone with wrist pain problems.

Having said that, this mouse have weird problem of being *heavy*. They did this on purpose, I dont know why - probably to "feel" more expensive. Inside, they have two additional weights (see photo), which add noticeable strain on wrist. Also, sometimes you need to pull the mouse up, and it is very hard to do, so you accidentally press those additional buttons on the left side and your browser page disappears - all because they added these two bricks inside

Good news is this is fixable, just open up the mouse (two additional screws sit hidden under two "sliders"), there should be 4 screws total - remove bricks and enjoy

UPDATE 2, after 10 months.

Mouse wheel started to fail, I disassembled it again and checked it. It turns out it actually *DESIGNED TO FAIL* with the time: rubber "tire" will lose traction with the plastic wheel, supporting it. Good news is - this is fixable too, if you "loosen" stopper that holds the wheel. As the result, mouse wheel will start working again, but you wont hear the click anymore (I still dont understand why they needed it in the first place). So now mouse is working great now.

Overall it is crazy that customers have to remove stuff from products to make them work better ...

The mouse feels good in my hand and helps reduce my wrist tingling. The sensitivity of the movement of the cursor is accurate. My only peeve is the same one others have pointed out. The buttons by the right thumb are too easy to click. The bottom button is the one I click most often and this is the page back button. Meaning, while I'm in a web page if my thumb hits that button, it's like hitting the back button. I lose whatever I'm doing in that page and goes to the previous web page. This is a known issue with this device but the developers don't think it's a problem. There should be a way to set up the buttons or turn them off, which is what I would prefer. For the price, this is a well made device but the developers should listen to their customers and fix the thumb buttons.

3 stars or 4. Hmmm. I'm confused by this mouse. I have severe shoulder, neck, wrist and finger pain in both hands, and have been forced to more often use my left hand (i'm a righty) just to give the right a break. So I'd prefer to have a lefty option, but that is not available. The major problem i have with regular mice is that my little end fingers try to clutch the mouse to stay in control of it. And mice have gotten so tiny these days that there is too little to grab. I am a woman with a small hand. I think this mouse is made for my size, and seems like it would be difficult for people with larger hands to use comfortably.

As a right handed mouse it doesn't seem to orient to my hand right. If I put the mouse in my hand as shown in the pictures - with my thumb firmly over the thumb area and fingers set about where the buttons are, I have to twist my wrist backwards in order for North South East West to be correct (like move the cursor correctly up, down, left, right). Picture pointing thumb straight out so that it makes a straight line down your arm. Then fingers to backwards to wrap around. That puts a lot of stress on my shoulder and strains through the back of my fingers.

If I rotate the mouse so it's not in exactly the right position on my hand but is in the right place North-South-East-West wise, it sits comfortably under my fingers BUT I can't scroll because the bar is basically where a ring on my middle finger would sit (because it's rotated 45 degrees). Far too low to move my finger to scroll.

If I can find a way to reorient the directional, this mouse would have a lot of potential. It would be a much better mouse and a much more natural position if the pointy end was set to NorthWest instead of due North.

Accuracy wise it seems very good. It's precise, and doesn't skip around like some cheap mice. It auto-detected really fast on both PCs and worked right off the bat. I'm not sure the dpi button is doing anything (on my other mouse it makes the cursor very slow, but I don't see a noticeable difference here). On the mousepad it moves fairly freely, but with just enough friction to allow you to stay in control.

I haven't had it long enough to say if it will help with my pain. I wasn't expecting much out of this, so I'm pleasantly surprised so far.

Keep in mind that with any mouse of any type, if you want any precision you need to steady part of your arm and hand on the desk while mousing. On this mouse your hand sits on the mouse, so for precision I have to lean my forearm or edge of my hand onto the mousepad.

I think this has potential. Worth a try if you have pain.

I have tried Anker and a few other vertical mice.. All of them are horrible compared to J-Tech.
But even J-Tech's has not reached perfection.

Pros:
--excellent button placement! not as hard to click as Anker's
--excellent removable rest pad
--great verticalness--even MORE vertical than Anker. holding position feels like you are grabbing a glass of lemonade

Cons:
--scroll wheel doesnt have a click.. it has an inconsistent texture when scrolling. slightly bothersome when scrolling a lot
--i'd like to be able to remap the dpi button... the past 3 mice ive bought have all had a remapping software with full-fledged macro. but they were not vertical of course.
--it feels a little uncomfortable but i do not feel ANY wrist strain. Despite the comfort, I KNOW that it is good in the long-term to get used to holding the mouse like this.

I can honestly tell you after Anker and cheap $10 vertical mice... this is the best mouse out there right now!

Excellent mouse if you are left-handed. I bought it when I broke my right arm. And the price is great too.

This lefty mouse works just as good as the one I had before that cost $100. I definitely recommend it.

Excellent quality for the price, soft -click buttons, fits comfortably in my hand. No more pain from traditional horizontal mouse.

Takes a bit of getting used to, need mousepad to cushion that bone where wrist now rests. But I like it, does indeed help.

I'm so glad to have found a decently priced left-handed upright mouse. It works great, too. Plug and play... no hassle install My only regret is that it doesn't have the two additional buttons and a clickable scroll wheel that my right handed mouse has. It's nice to be able to click forward and back without having to actually click a target. But given that it's substantially more reasonably priced than others, I'd buy it again.I pity the poor lefties out there. This "bare bones" mouse cost about the same as my 5 button right handed upright mouse.

The presentation in the product is what I expected, however the grasp of the mouse can be improved given that the function is for more comfortable use.

Update: I got a message from Lugulake to give more information about how to improve the product, i think the biggest issue as I mentioned is the grasp, the material in which the product is made makes it difficult to hold on and work naturally, it's necessary to have a mouse pad to have a better experience.

Maybe if the back could have a little inside gap (for the thumb) could help.

I read all the reviews before purchasing it, but in the end it just didn't work out in my case. The main thing with me is that it is just too big for my hand. I wish they make it a tad smaller and shorter. It just didn't feel right as my hand keeps slipping off towards the back of the thing and I was having a hard time moving it because my grip is not in the right place and end up straining my wrist more because of the angle it is in. If you have large hands, and I mean a man's hand that measures 9" or longer from tip of middle finger to bottom of palm, this might work out better for you. My hand measures 7.5" and my middle finger only reach the middle part of the right button.

I bought one to try out the ergonomic benefits behind these vertical mice. While the mouse has performed well for the past few months, in the end I went back to my old Logitech G400s mouse. My main issues with this mouse were:

1. No wrist support. Your wrist drags along the tabletop, and this seems to introduce about the same amount of wrist pain as a traditional mouse for me. You have to rest your palm a certain way on the top of the mouse to give your hand some support.
2. Difficult to use middle scroll. Not sure if this is related to vertical mice in general, but it seems more difficult to reach the middle scroll wheel in this hand position.
1. Missing side back/forward buttons. It's nice having these for web browsing / gaming.
2. Button / scroll wheel quality. There's quite a bit of wiggle with the buttons. The scroll wheel is not snug and moves side to side.

Overall for the price though it's a solid mouse, and if I didn't have a fairly ergonomic traditional mouse already, I would probably continue using it. I may end up buying a higher quality vertical mouse in the future that addresses the above concerns.

The mouse feels good, but the flaws make it hard to use.
Pros:
The design prevents wrist pain
Cons:
The buttons are hard to press and stick
The scroll wheel is sticky
The left mouse button is so far to the top that when resting your hand on it you will click accidentally
The weight is near the top, making the mouse easy to knock over

Overall, it is a good concept. But the endless design flaws make it a tough sell. If you have serious wrist pain, then this is the mouse for you. If you are just looking for something new, I would suggest that you look for something else.

EDIT:
I added a star, because for the price it is not bad... And they messaged me to try and get this resolved. But I would still not reccomend this so anyone.

This is a perfectly fine little upright mouse, and might come as a revelation to those who never used the revolutionary Evoluent Vertical Mouse. It is inexpensive and works perfectly. Looks nice. It is worth the very low price.

Let me now explain why you might want to pay a lot more for a proper Evoluent Vertical Mouse (EVM):

The EVM supports your whole hand and leaves nothing resting or dragging. I have small hands, and when I use this mouse I have 2 fingers that have nowhere to go, that I don't know what to do with. I do not just move my mouse a teeny bit, I need to roam with my arm and the Lugulake doesn't encourage me to do that.

EVM has many programmable buttons, this mouse has two buttons, only two, nothing but two. Be honest with yourself about what your computing needs are. If you have a EVM you can use only two buttons if you want, but you have choices. This mouse, you have no choice.

Don't pay more if this mouse is truly all you need. But if you need something better, splurge and be good to yourself. If you are buying a vertical mouse for health reasons, don't be cheap with your health.

However this mouse is smaller and more portable than the EVM. I will keep the one I ordered as an emergency back-up mouse.

It's weird! I keep knocking it on the floor when reaching for it because decades of flat mouse use have trained me where to reach to I hit the tip often, moving from keyboard to mouse. Moving it left and right is super easy. Moving forward and back OK. Wheel, Front/Back buttons, all good. Design is interesting and lighted area is not too bright (a positive if you've had lit mice that keep you up at night!) Anker's a good brand. Only other thing is pinky doesn't know where to be. Poor pinky...

I received this as a gift from a buddy of mine in 2016. Unfortunately, I forgot exactly when, but it was in the early half of 2016. If there was any paperwork, I've probably lost it by now. I really liked how comfortable this mouse was, but was ultimately disappointed. The cable seemed a little flimsy, but that wasn't such a problem. The worst of it was when, a few months after using it, the scroll wheel became utterly useless. Shortly after that happened, the scroll wheel became hyper-sensitive or something--if I so much as brushed the wheel with my index finger, even left-clicking became a hassle. So, I binned it and went back to my first Anker mouse (which lasted me a little under three years with no real problems).

Looking at some of the other reviews, it may just be that I got one from a bad batch. As you can see, mine matches the old type (pardon the dust, because I've only found time and presence of mind to write a review, now). Given my experiences with Anker, so far, though, I'm definitely willing to give them the benefit of the doubt. The first mouse was pretty good, after all, and the USB hub I picked up still works well, too. I don't expect a replacement, though, given the muddiness of my situation. In the future, I intend to check out the newer--and hopefully improved--version, one way or another.

I have an average size female hand (medium when buying Smartwool gloves). The scroll wheel is a real stretch. If I position my hand so the wheel is comfortable, the forward/back page buttons are awkwardly positioned for my thumb. I tried using it for a while, thinking it might just be an issue of getting used to it. But no. physics trumps all. It's also narrowly shaped, so it's like grabbing a sheaf of paper using my thumb and forefinger. I'm used to using the fatter Etekcity ergonomic mouse and that's much more comfortable to wrap my hand around. The Anker looks good and the smooth rubberized coating feels nice, but it's just not really designed for me. Unless I find another taker with larger mitts, this one's going back.

UPDATE: Anker got in touch and sent me a newer model of this mouse to review. Second mouse is better as it's wider and I don't feel like I need to crab-claw so hard to use. I tried it off and on for several weeks to give it a fair shake. Not a fan of the forward/back buttons placement. They are both located "up" of the thumb, one further away the the other. This means if I want to forward, I have to reach farther with my thumb than if I want to go back in my browser. The placement of the button was a little awkward. When I click use either forward or back button, I squeeze and will frequently accidentally left click. Tried training my hand to brace on the bottom of mouse and the top to avoid this, but ultimately isn't my working style. Gave it to a colleague who is trying it out. Thanks, though, to Anker. Awesome customer service!!

UPDATED BELOW:
Fairly comfortable (though too light, which makes it tend to tip), relieves worst of carpel tunnel, decent texture and scrolling when new. But after having it for a year:

-the scroll is not always responding;
-it takes 30 sec - 1 min to start working after computer sleeps (never had this with any other USB mouse);
-the light on the side is cutting, often flickering;
-the Anker badge is bubbling.

In short, it's poorly made. I'll spring for a better mouse next time.
--------------------------
UPDATE: Apparently, this mouse comes with an 18 month warranty. (I suppose I should have known that.) Manufacturer kindly reached out to me and sent me a replacement. This replacement, so far (about a month), does not display any of the four defects enumerated above. Time will tell how it lasts.

There have been a couple of changes that are noteworthy:

-The light on the side is no longer blue but red. (For me, I'd just assume not have a light, since, as with similar devices, it stays on when your computer is off so long as it's powered -- meaning, bright lights in the room at night.)
-The plastic on the body has a slightly different feel: somewhat softer to touch. I prefer this feel to the previous, and I wonder whether (hope that) it will be more resilient.
-The scroll has slightly less resistance as well.

If, as the manufacturer claims, the prior device was defective and this replacement will last better, then this seems like a great, inexpensive handshake mouse (worthy of a higher ranking). I'll update this review after some time accordingly.

I just got this new Anker. I must say I bought it without much doubt, seeing it had a lot of positive reviews. After a full day of use use though, I am not fully satisfied with my purchase. Here is why:

PROS:
• Design: sleek, elegant.
• Touch feel: comfortable, classy.
• Confort: fits nicely in the hand.
• Tracking: good tracking in both modes.
• Price: for sure, the mouse is good price for quality.
• Solid mouse: the mouse feels robust and has a perfect weigh.

CONS:
• Buttons: this is without any doubt a -1 or -1,5 star. They are, as other said, quite hard to click, which is paradoxical for a mouse that pretends to be ergonomic. Maybe my product has a default, but I had a Logitech mouse before, and I can tell these buttons take nearly double pressure to click. I let you think of all the clicks you do in the day to consider the impact it can have on your muscles over a long-term use. And I know there is a happy middle between too hard and too soft. But considered this problem has been highlighted in a lot of reviews, I wish Anker adressed it.
• Ergonomics: this is a -0,5 or -1 star. Although the mouse feels good in the hand, the angle is maybe not optimal. As others said, it is not a fully vertical mouse. So your hand is always in an in-between position: it doesn't benefit from the full vertical position – where you can relax your arm in a vertical position – nor does it allows your arm and your hand to rest in a flat position – the one you have with normal mice, although this position causes wrist and forearm pains. To add to this problem, I can say after one day of use that I have started feeling a real pain on my ring finger – a pain I have never felt before – that I link to the fact the mouse pushes down your ring finger and pinkie, knowing the mouse is low for people with long fingers/big hands.

OVERALL
I would say price for quality appears to be good. But the product doesn't deliver on its promise according to me. Buttons are way too hard to push and the mouse could be a bit more ergonomic. I wish Anker took into consideration this feedback – knowing I am not the only one to support this view – to make its product better. I haven't tried any other vertical mouse yet. I thought I could fully rely on this buy, but I am now considering moving to Elekcity or even Evoluent.

[EDIT]
After my review, Anker followed up with a customer support email. I must say their support has been very good. I feel like they are really caring about customer satisfaction. So, although this won't change the product and my review, it's really a great plus in their favor compared to other brands.

I really wanted to like this mouse, but it just doesn't work for what I need. I mainly wanted an ergonomic mouse for gaming because using a regular mouse makes my hand sore after a while. The problem with this mouse is that it's just not accurate enough and it's harder to move it quickly, which is really important for gaming. You just don't have the same range of motion with this mouse as you have with a traditional mouse. I also found that while this mouse was more comfortable for my hand, it was uncomfortable in other ways, particularly in how my forearm rests on the edge of the desk. When using a traditional mouse the fleshy under portion of your forearm rests on the desk. With this mouse your arm is in a "hand shake" position, so the bony part of the right side of your forearm rests against the desk. I had to put a wrist pad under my forearm for comfort, but this restricted my movement even more. I think this mouse would be fine for normal computer activities, but it doesn't cut it for gaming.

If I could figure out a way to disable the forward and backward buttons on the thumb side I would give it 4 stars. I don't know that the shape is great, it's just different, and when it comes to repetitive motion injuries (like carpal tunnel syndrome) different is useful. What kills me is when I'm entering data on a form and grab the mouse and accidentally hit the back button. BOOM! All data gone. Start over. Grrrrr.

It only took a short adjustment period to get used to it (other than the forward and back buttons under the thumb). I haven't gotten the DPI button on top to work, but I haven't put serious effort into it. It's ok, but if it died I would replace it with something else.

The first mouse I got the red laser in the base was very, very weak. I had to look carefully inside the laser window on the bottom of the mouse very closely to see that it is barely red.

The mouse was having issues losing communications between the surface of the mouse pad and the laser.

It's a good physical product execution as far as ergonomics go, I can already feel some relief from what was becoming a carpel tunnel issues that was exacerbating weight lifter's elbow. Having the hand in the "handshake", neutral position relieves the constant small amount of tension in the forearm extensor muscles associated with the prone hand position over a mouse.

Nathan at customer service responded to my review here promptly and sent me another mouse, it seems to be working well, and most noticeable, the mouse glides over the mousepad much easier than the first one.

It's a good mouse, but, the position of the thumb, especially for a normal sized male hand is directly between two buttons above the thumb which are the back and forward buttons for the mouse.

When you are working in a smaller mousepad area, (like most workplace situations), and where you are working with multiple screens especially, (like many workplace situations), one must lift the mouse to get full functionality across the screen, and when you lift this mouse the thumb can easily hit the back and forward buttons which is quite frustrating.

An applet should be written to disable these mouse buttons. The mouse is rather heavy, so considerably more force, (although still little force), must be exterted on the mouse to squeeze it so the thumb does not ride up into the back/forward buttons and activate them. This is a tension creation point. If you use the mouse with a completely relaxed hand, your thumb is going to hit those buttons, at least every now and them.

The whole point of an ergonomic mouse is to minimize any clenching or holding of the mouse while operating the mouse so the thumb buttons that are so close to the thumb, and because the thumb must be used to lift the mouse up, that's a subtraction of a star for me. The first mouse being defective is a subtraction as well, so three stars is fair.

I really like the ergonomic design, the handshake position, and the added texturing on the mouse does assist with lifting, but again, the thumb is just too close to the buttons that the thumb can so easily contact when lifting the mouse.

One plus for the design over the other vertical mice is the added palm rest that slides over the mouse surface.

I think there is a period of time in which this mouse must be used to simply develop the muscles and fine dexterity required for the new orientation and I may raise the stars to four if I can get more and more accustomed to the design. But the thumb buttons are still a big issue. Remember, it's a mouse that is supposed to be much, much, much more comfortable to operate than a standard mouse, so the thumb buttons really do hurt the design.

I bought this mouse because I already owned the Anker vertical mouse (2nd edition), but I wanted to see if there were more ergonomic vertical mice on the market. While I like the design paradigm of this mouse better than the Anker mouse, the Anker mouse somehow accomodates for the size of my hand better than this one does (even though the Anker mouse is smaller).

My hand rests on the buttons of this mouse so that the buttons are underneath the knuckle closest to my fingertips, rather than my fingertips themselves. Also, my pinky gets squashed into the rest of my other fingers by the lip on the bottom of the device. The Anker vertical mouse provides more space for my pinky because it doesn't have a lip on the bottom. The Anker mouse's large buttons also accomodate for a range of finger lengths better than this mouse's smaller buttons. Because this mouse is designed for a smaller hand than mine, using it is awkward (and will probably be painful if I use it often enough).

My hand is 7" from base-of-palm to fingertip.

UPDATE 9-14-16: The shape of this mouse is so perfect that I bought a second one, but after using them all day every day for less than a month, I found the switches did not really hold up well. It became harder and harder to get a solid click with a light press. It developed a two-stage click feeling, and when pressing lightly I could feel a click, but that click did nothing. Pressing harder worked fine most of the time, but for me to feel like I was guaranteed a real click, I ended up having to press carefully, at a specific angle, with a very solid press of the finger. And the click did not feel right. It was manageable given how much better my wrist was, but then I got an Anker vertical mouse and the buttons were so amazing that I switched to that. However, I modified the Anker because the shape is not nearly as good. I added a 1/2-inch foam pad to make it wide enough (this helps keep the correct wrist angle). I think this mouse might be fine for people who do not do as much mouse work as I do, and maybe I just got some from a bad batch, so I don't think this is a "bad" mouse it just seems like it would be amazing if the switches were better.

ORIGINAL REVIEW (was 5 stars out of the box):

Great mouse! My wrist is MUCH better!!

I've only been using a few days but I really like this mouse now that I followed Novosib's modification (March 5, 2016) for removing the weights. I also removed the optional palm rest. Without the weights and palm rest, I can make much smaller hand movements and have much better accuracy and speed. I can also pick up the mouse more easily to reposition it.

The problem before was accuracy and speed of positioning the cursor perfectly. I have three 1920x1200 monitors so I need a fast mouse speed setting to move across all that screen real estate, but then I need to put the cursor EXACTLY where I want it once I get there (graphic/web design work).

I think I will become just as fast with this mouse as I am with my regular mouse. I'll try to come back and let everyone know.

NOTE: Since Novosib's review they may have added the optional palm rest, so you need to remove that to see all four screws he talks about. Once you remove the palm rest (just gently pull it straight back) you will find two screws under it. The other two are under the larger stick-on sliders.

I love it without the palm rest and the weights! I'll be buying more of these for sure!

The buttons have a hard click. I need a soft click, vertical mouse due to ulnar nerve pain in my arm. I had to return this because it was too painful for me to use. I bought a more expensive Evoluent vertical mouse, which has a softer click.

Very comfortable in the hand and worked great until the little pin that operates the mouse wheel broke. Fixed it with a machined bit of an old knitting needle. Probably not the best design for ham-handed lefties like me, but if you've got a light touch, this is a great mouse.

Does what it's supposed to do. Cheap feel, but works OK.

Suffering from carpal tunnel in both hand I was looking for a vertical computer mouse to help with some relief I don't find with the conventional mouse. I'm also left handed and as expected, there is not a whole lot of selection for our kind when it comes to vertical ergonomic mouse. And I didn't want to spend a lot of money for a left handed mouse I wasn't sure I would be able to use and help with my issue. In the end, settled for this one. Quality wise it seems to be comparable with the Microsoft mouse I was previously using. Due to its design, it take a bit to get used to handle it. Because it is grabbed at a different angle I don't feel much of the strain I get with the conventional mouse. The only reason I'm not giving it 5 stars is because it is not customizable. My computer, while allow me to use it as it is plug and play, it would not recognize it and therefore you can't select which button to be the default button for left of right click. Overall it is a decent mouse for the price.6/21/17 Update: after nearly two months of use, the wheel broke and rendered the scrolling feature inoperable. The left and right buttons still work, but the fact that the wheel broke cast a shadow of the quality and reliability of the product.

Its OK, but I prefer the evoluent product line much better. This mouse just feels cheap and unrefined. There are also fewer control buttons so you have to use the keyboard more often or right click more often.

The mice works great and feels comfortable. However it only last 3 months unfortunately before the middle button quited.

When I received it 10 months ago, it worked great. Loved how it was easier on my arthritis. But yesterday, it up and died. I cleaned the lens, the mouse pad, checked connections several times, and it doesn't work. $10 for 10 months isn't bad, but I spent an hour and a half googling how to fix it, and it's not fixed.I also called Lugulake but they must be closed for Good Friday weekend. I got my $10 worth, but now I'm ordering an ANKER brand. I'm hoping that's longer-lasting than 10 months....

05/01/2016 Update - Had to update my review because after my second LuguLake mouse, problems arose even quicker with the scroll wheel, so it wasn't just an anomaly with the last one. This time, it got stuck in "scroll-down" mode and became useless after that. LuguLake if you are listening, fix your scroll wheel and MAYBE I'll come back to this product. Otherwise, I recommend against this mouse.This is a good, functional mouse that really did help ergonomically with the many hours a day that I use it. It's a huge difference when I have to use a regular mouse now. I would have given it 5-stars, however, it only lasted a year before the scroll-wheel broke and I had to order another one. But I use it heavily at work, averaging 8-10 hours a day on weekdays and some on the weekends as well, so not going to dock it too much — especially for the price.

I had a case of "tennis elbow" (tendinitis) which my doctor could not explain. After some research I discovered that here is such a thing as "mouse elbow" caused by use of a standard computer mouse and scroll wheel.Tried this mouse and immediately felt some relief; after a few weeks, the pain (more in the forearm carpal area) was gone.There were some problems with the first mouse, mostly related to the wires inside the cable breaking. I contacted the seller and they sent me another, which worked flawlessly, at first. I was so attached to the first one I tried soldering in a higher-quality USB cable, but it did not work. Eventually the second one had the same issue. Turns out this mouse uses a non-standard connection in the wire colors. (The red and white wires are reversed from a standard USB plug.)Now it works perfectly, though I'm not entirely certain which of the mice I have connected to a better wire now. I hope it holds up for a long time.UPDATE: The second mouse has now gone bad, with wires broken within the cable. Tried soldering in a new USB cable from a discarded USB device, which might have worked if the wire colors inside the case of the mouse were standardized (red and white were reversed). Now the click buttons don't work because the ribbon cable inside the mouse has now separated from the PC board. Too bad; really liked this mouse, but won't buy another.

Larger than normal, it feels a bit clunky at first. But after a few days you get used to it and it is the most comfortable mouse I have ever used. The buttons have the correct resistance. You don't have to hold your hand at an unnatural angle, Everything works well, It tracks well on just an old Formica desktop. No extra weird buttons to memorize. The scroll wheel works great. My favorite mouse to date and it was only about $8. Highly recommended.EDIT: Reducing this to two stars. I love the ergonomics of this mouse. But for some reason when used with my Windows 7 computer it will often disconnect for no apparent reason. The computer makes the same sound as when unplugging any USB device. Then 3 seconds later it will reconnect by itself and make the "connecting" sound. Very annoying. I liked it so much I purchased two and they both do the same thing - not a bad cable or connector - it must be a bad circuit or design. Using the stock Windows 7 mouse driver. Not recommended.

I have an Evoluent mouse which is very good but also kind of expensive. When I saw the Lugulake and it's very affordable price I figured, what the heck..I will try it. Well, after using the mouse for a couple of hours I noticed that the angle of its design kept a portion of my hand (where it meets the wrist) to rub constantly on my work surface and that area started to get sore and tender to the point that I had to stop using the mouse. If the manufacturer were to change the design (slightly) and put some sort of "lip" for that portion of the hand to rest on I think that it would solve the problem. Either that or make the angle of the controls more vertical (like the Evoluent) so that the entire side of hand rests upon the work surface distributing the weight and eliminating tender spots. Other than that it is a very promising design. It just did not work out for me.

I work in IT pulling 12 hr shifts and at the end of the day using a regular mouse my wrist would be aching. So I decided to look for a more economical mouse to use at work and this one fits the bill. It tilts your hand to the side relieving the direct pressure experienced using a standard mouse. It has the 2 standard buttons and a scroll wheel, nothing else, so it's basic but works. It does take a day or two to get used to the feel. I have also had the problem other reviewers have referenced and after some extended use the usb cable began to pull away from the mouse, despite there being no pressure on the cable. I do like the ergonomics but I would recommend finding another product.

This is almost a GREAT mouse. The sideways upright buttons help so much for your wrist. The problem is your hand slides off of it. I tried it for a week and it just would not feel comfortable. Your hand struggles and stresses to stay on the mouse that it causes another pain in your hand. If they made the side you grip with rubber or something less slippery and extended the mouse to rest more under your hand - it might have been better. I returned this item. I ordered the J-Tech Digital wired mouse and will try it. It has rubber side and extended under your hand so it seems you won't slip off of it as much. If Anker does a little to fix this mouse - then it would be great!

I didn't realize how much I depended on gravity and the desk being a counter to my button clicks with a standard mouse. The angle is too great on this mouse, so you have to squeeze the mouse to click it. It's possibly perfect if you are a crab.

If you want hand cramps over carpal tunnel then this could be the mouse for you.

Double clicking is bothersome since the mouse tends to slide during the clicks making the computer not recognize the action. Even single clicking doesn't feel precise because of the way the mouse moves with the pressure. (Of course with a "normal" mouse, there is less motion because the movement of the mouse is resisted by whatever surface it is on.) I'm surmising these are general problems with vertical mice. I did not know about these issues or I would have stayed away from getting a vertical mouse. If you are not bothered by these design issues, then the mouse is good.

Not in love with this mouse. I've used vertical mice for many years now and when my DXT started having clicking issues from it's age I tried something new. I have cubital tunnel syndrome - similar to carpal tunnel but in your elbow. This mouse exasperated it to the point where I could not bend my fingers they were in so much pain. I think the issue is the size of the mouse. To use it you have to have a "grip" on it and it's so large for my small hands that it feels like I'm holding something all day as I work. I ended up paying the extra money and going with DXT again and within a few weeks my arm was back to normal.

Not a mouse for everyone. I was looking for a mouse to use since I do CAD design for 8-12 hours a day. While the mouse provides comfort to your wrist due to the angle, I felt the buttons were hard to press. This was more so prevalent when using the scroll/pan wheel. I use the pan feature a lot in CAD, and it becomes tiresome and wearing on your pointer finger due to the angle and pressure needed to press down the scroll wheel. I would recommend the mouse for the average office user but not for someone who uses the pan feature a lot. If they were to revise this so the scroll wheel was easier to press, I would rate it 5 stars. At this point I am considering to return it since I can't use it.

This mouse does not work as well as I had hoped because the scroll wheel starts to malfunction after about a month.I initially bought this mouse to replace my standard, non-ergonomic mouse at my office. After about a month, the scroll wheel began to not function properly; on screen it would scroll in the reverse direction, or get stuck between points and rock up and down without continuing in either direction. This made it extremely difficult to do my work. I thought I had a defective product. J-Tech was gracious enough to replace it in kind free of charge.Using the second product, I had the same grace period of about a month in which I did not experience any problems. Now this mouse is doing the exact same thing the last product did, so I am really disappointed with it.The only good thing I can say, having experienced all of this, is that the customer service department was prompt to respond to my problems with their products. Upon returning the bad mouse free of charge, they provided me a full refund in a timely manner.

I wanted to like this mouse because my classic mouse is causing pain in my forearm, but this mouse isn't the solution. For one thing, the large baseplate produces a lot of friction and makes it hard to move the thing around, regardless of the kind of surface I put it on. I read one review that suggested removing the wrist rest to reduce the surface area, but I figured if I modified it I wouldn't be able to return it, so I didn't try that option.I also found the inability to use finger movements in positioning the mouse made it very difficult to use. Imagine trying to write a letter with a pen gripped in your fist and you'll get what I mean. You could do it, but it would be pretty slow and painfully imprecise. This mouse has many positive reviews so a lot of people seem to be able to make the transition, but I guess I lack the patience to try to get there. I want to put my effort into my work, not to positioning my mouse.

I liked how the mouse felt in my hand, and the concept is spot on, but the execution is not so good.After owning, and using this mouse, for a whole day (GASP), I was not pleased with it.The mouse itself was very light and moved well, but the buttons on the mouse felt very cheap. I'm a PC gamer, and the left click on this mouse was terrible. Each click felt like 3 or 4 clicks, and sometimes it wouldn't register a click or double-click. It also seemed to have that plastic creak to it when using the buttons. It drove me crazy, and I decided not to keep it and return it.

Considering that this is not an expensive mouse, it does the job well to keep your hand in it's natural position when you are handling your mouse for many hours. Here are some ratings from 1-10Fit in the hand: 9 Fits very confortablyRight and left clicks: 10 very responsive and does not take much effort like other miceBack and forward buttons: 2 (I keep clicking the back button accidentally when I grab the mouse so had to disable the buttonPositioning: 8 Takes a bit getting used to as after using a standard mouseScroll Wheel: 0 The scroll wheel is just ok. It does the job but doesn't have the effortless feel of a logitch mouse. This one has an ordinary, cheap mouse feel to it.Update November 5th. 2016. After a very light use, the scroll wheel has stopped working. Never had a mouse "wear out " on me!

I purchased this after reading all the great reviews and was in the market for a new ergonomic mouse that would hopefully alleviate the pain I would get now and then in my wrist due to extended mouse use at work. Unfortunately I don't think it worked for me.Pros:- Vertical mouse feel.- Would work best for medium sized hands.- LightCons:- The construction feels a little too plasticy and cheap.- The surface of the mouse seems to easily sweat up, and although I don't profusely sweat on my palms, the mouse seemed to feel slippery when holding it.- The left and right mouse buttons are oddly placed. It might work for some, but definitely when I rest my hand on the mouse, the buttons are slightly off and I have to tense my hand to keep it right on the buttons.- The scroll wheel is a bit of a stretch when you are using the mouse.- The back and forward buttons are too easy to hit based on your thumb position.Over all I feel more than relaxing your hands, you have to grip the mouse to feel you are in control of it. My search for a good mouse still continues.

April-I had palm and wrist pain and my arm and hand would go to sleep before but now I have no problems. I adapted to the change really well. It did take getting use to, had to slow down a bit while working but after a few days I was using this product as if I always have.This is an update. I started having problems with the mouse not working at times last month and then this month, "June" the mouse completely stopped working. I had to go back to the regular mouse I had on backup and my wrist already hurts. I am totally bummed!Purchased April 2015 and it stopped working June 2015.

Bought beginning of March. Broke beginning of August. A thin plastic piece of the wheel that spins inside a sensor broke. Aside from this it was good and worked fine. May be the plastic piece was defective. But looking at it, I would have made it stronger (thicker in diameter).

Worked well for about 3 weeks, then the scroll wheel stopped working. I took it apart to see what the problem was. The scroll wheel's axle sheared off between the wheel and the encoder. Poor design, the scroll wheel needs more support. Won't be buying a replacement.

I have bought this mouse many times in the past for work and it performed very well. This last shipment came with cloth-covered wires, I was so excited. However, the quality has dropped. After just a month of use, the left-click now sometimes registers as right-click on the screen. You can imagine how infuriating this is while trying to draw diagrams in photoshop!Mouse died right after a month so I can't return it. :(

Tried using it for several weeks when I first bought it, then put it away, due to it actually causing my more strain on my hand than before. With both carpel tunnel and tendonitis in my hands and wrists I was hoping that this mouse would help alleviate my problems, but only seem to cause more pain when used for long periods of time.Recently I pulled it out and tried it again. This time it only lasted a day before I had to put it back away. I've come to two conclusions why this mouse didn't work for me:1. I have large hands. With no support for my ring and pinkie fingers this caused discomfort after relatively short periods of use.2. While there are locations on the bottom of the mouse for small, teflon tape feet, no feet were installed on the mouse and no sign of ones I had to apply myself in the box it came in. I finally realized that without teflon feet the mouse drags on the tabletop, causing extra stress on my hand and wrist. Couple that with the smaller size, this mouse just fails to deliver what I needed at all.So my thoughts, with the addition of the missing feet it might be an OK mouse for someone with smaller hands. Maybe. It's just really bad for me.

I bought this nearly a year ago, but I'm writing this several months after this wound up in the trash. I bought two vertical mice for my two computers to deal with my rotator cuff issues: this one, and an identically shaped one that cost about two times as much.Both functioned well in regard to relieving the pain I feel when holding a standard mouse. From the beginning, this one felt cheaper, as expected, from the construction of the mouse itself to the thinness of the USB cable. But despite being on the less-used computer, after about 8 months the buttons started malfunctioning unacceptably and the product became useless to me. This product appears to be part of that family of devices that seem to have been engineered to fail within a year.

I should have read the reviews carefully. I think people should wait a little longer to make a review instead of judging. This especially applies to products used incredibly often, such as with mice. The scroll wheel, as said by other reviewers, failed and when I emailed the support, they offered a refund of $6, about one-third the price I spent for it ($9.99+ $8.32 S+H=$18.31). Though they say that their warranty lasts a year and my order is within a year (7 months ago to be exact), they wouldn't replace it and offered the $6 refund or a replacement for $4. I wouldn't trust a new one to last so I opted for the refund.My next purchase will probably be either the Anker mouse or maybe a Logitech trackball mouse but I'm not particular on using a ball or the $30 of the Logitech. I hope the Anker doesn't have the scroll wheel problem but they have an 18 month warranty.

I bought two of these mice recently. Withing 30 days of using them BOTH of them have a broken scroll wheel.I took them apart to see if I could fix what happened, but the pin holding the scroll wheel is small, small, plastic and broken. This causes the scroll wheel to fall out of its holdings and not allowing the mouse to read your mouse wheel scrolls. Both of the primary buttons still function.Great price, but as two of them are broken within 30 days I wont be buying anymore.

This mouse does everything it is supposed to do and will help to reduce problems with wrist and arm soreness. However, it is not compatible with all computers. On one of the computers I use, the mouse started sending a click signal whenever I hover the mouse over a link or icon. It does not do this consistently. It has caused me to send emails prematurely becuase the mouse passed over the "Send" button. This product is billed as "plug and play" and there are no driver updates provided at the manufacturer's site.I replaced the mouse with a standard traditional mouse and the problem went away, proving that this is not a configuration problem with the PC, but a compatibility problem with the mouse itself.

Side buttons are basically useless, and there is no feedback when pressing the dpi button. Apparently, the wireless model has a blinking light to help you figure out what dpi you're in. The position of it also means you click it by accident all the time.

Accuracy is poor, double click doesn't really work.. I bought this a week ago and have already replaced it.

I think the hype reviews are from users who have never used a decent mouse before, or place ergonomic shape above function.

This mouse ended up irritating my wrist because the 'pinch' action that is required to hold your hand o the mouse properly is not ergonomic.

I've only used it for 10 minutes maybe, but it's already hurting the muscles in my hand. My wrist may be better off, but my hand isn't.

After using this mouse for a week, I felt like it actually made my hand felt worse than using a regular mouse. I have used vertical mouses before and loved them, but I had a horrible experience with this mouse. While I saw the reviews saying the buttons were hard to press, the combination of necessary force and the mouse shape/size actually exacerbated the pain. I had high hopes for this mouse, but unfortunately I won't continue using it.

After a few days of use, I already feel some relief from the ugly carpal tunnel pains that were hassling me.

The mouse wheel is a little difficult to press if your hand isn't in the proper vertical position. If you try to push down toward the desk, as I've done several times, it won't click, you have to press the wheel into the mouse itself, which feels strange. That aside, the wheel is just fine. There is a solid tactile feeling when you roll it - as a gamer, that was important to me. The buttons (5+dpi button) all have a nice solid click to them, there's no uncertainty about whether or not you clicked something.

The mouse is a little difficult to pick up when I need to move it back to the middle of the mousepad. It's so smooth that there's nothing to grip onto like a normal mouse. It's also a little on the small side. I have small hands and it fits perfectly but if you have giant paws for hands, you might want to look for something larger.

As a nice perk, it glows blue. I haven't seen a way to turn it off, but I wouldn't turn it off anyway.

All in all, very satisfied. I would recommend it to anyone that wasn't sure about vertical mice but wasn't sure about investing a lot of money.

[UPDATE] - October 1, 2014

The mouse wheel broke during regular use. A part inside snapped and now it isn't slotted in the mechanism that reads wheel rolls. At the same time, something else must have broken because the mouse movement on screen is now jittery and inaccurate. Extremely disappointed, it's essentially unusable. Without the mouse wheel, web browsing becomes physically painful, undermining the whole reason for getting a vertical mouse in the first place. At least the mouse was so cheap that it was pretty much disposable. However, for a product that only lasted roughly three months, even that is inexcusable. Reduced stars from 4 to 1.

For those who move the mouse around, it may not be comfortable as I found I had a hard time lifting the mouse to move it where needed on my dual screen setup. The size was a bit larger than I expected and did not fit in my keyboard tray. (see pictures). Trying to put the cord over the desk since I could not get it in the keyboard tray made the mouse lift at the tip at times as the cord would get hung up. I don't have the option to leave the keyboard tray open indefinitely and run the cord through the keyboard tray, as normal. I also found an ergonomic issue, where my finger had to curl up fairly far in order to move the wheel fully. Compared to my previous mouse (seen in the pictures for comparison where I put my finger at the end of the wheel), it was uncomfortable to use it this way and trying to use the wheel with different fingers did not resolve the problem. I have average size women's hands and it felt too small as I would have liked the wheel further out from my palm. I also ended up hitting the buttons next to the thumb when trying to lift the mouse, which I suppose I could have tried disabling. This mouse was simply not for me.

Big bulky and very hard to use due to very large base I thought this would be comfortable to get my wrist off the mouse pad and onto the mouse however that increased surface area on any surface I tried and caused an increased drag thus causing me to expend more energy on my wrist which I was trying to elevate by using this. Big and heavy lots of surface drag caused excessive wrist pressure to use all day.

Mouse was slow and jerky, and the scroll wheel requires too much lift, putting stress on the back of my wrist. Removed it, and now my old mouse and keyboard barely work. Even system restore didn't fix it. I've uninstalled everything through device manager, and am staggering along, but I think I see a windows re-install in my future.

Revising this review to 1 star. Purchased November 2015. As of August 2016 the mouse is not tracking properly. I have tried cleaning, different mouse pad (surface and color), reinstalling driver, switching USB ports. Nothing helps, so I believe it is the product itself. Less than a year and I need another mouse. Would not purchase again.Original review below.

The buttons on this mouse click effortlessly, which is great on your hands, but makes it easy to click by accident - especially the thumb buttons. The palm rest was so miserable, I took it off after 10 minutes. Right, left, and wheel are fantastic. The wheel bumps as you scroll so it is nice and tactile, and the buttons are very smooth to click. They make the same click sounds as any other mouse. If you have carpal tunnel, this is a fantastic option. HOWEVER, it is so easy to accidentally set off the thumb buttons (backward/forward), it has caused problems for me. According to J-Tech's website/help board, there is currently no way to reassign or disable buttons, so I put a line of super glue along the top ridge of each thumb button so they can no longer depress. Unfortunately, I had to permanently take out half of this product to make it work well for me, and for that reason, it gets 3 stars.

Update: 8/12/15

So I've had this mouse for nearly 4 months and it has broken in the strangest way: One of the springs in the battery housing will no longer hold the battery in place.

I began having issues yesterday. It randomly stopped working. I thought perhaps the batteries were dying. I took the batteries out and put them back in and it worked again. Earlier today it did the same thing. Again, I took the batteries out and it worked. Then just a while ago it happened again. I decided that the batteries were definitely dying. So I took the batteries out, got new batteries, and put them in. When I put the second battery in, it felt loose. I turned the mouse over without replacing the battery cover and one of the batteries fell out. Odd!

I took the batteries out and looked closely at the battery housing. I discovered that one of the springs was completely flattened (see attached photo). I thought perhaps the spring was just caught at an awkward angle so I tried to tease it away from the side. That didn't work. So I got a toothpick and pulled it away from the side. That worked, but imperfectly. The spring is now distorted. I put the batteries in, put the cover back on .... and the mouse doesn't work. I tried opening it up again and ensuring that the spring was in the right place, not touching anything it shouldn't ... but no, the mouse doesn't work.

So while I appreciate the price of the mouse, I do really need it to work.

This is my second vertical mouse. My first one was MUCH more expensive than this (over $100) and was corded. Unfortunately, I have a cat who loves to chew cords - especially the small ones used in electronics and computer peripherals. So she killed my other mouse. I couldn't afford to replace my original vertical mouse and I also knew that she'd chew the cord again, so being wireless was VERY important.

I found this mouse and read the reviews. Some mentioned that it takes a while to get used to. I thought that I wouldn't need to get used to it because I was already accustomed to using a vertical mouse. I was wrong; this mouse does take some times to get used to even if you are already accustomed to using a vertical mouse.

It took me a couple of weeks to get used to the mouse and before I found it to be super easy to use. I do some gaming but mostly web browsing, writing and editing documents. I have arthritis in my hands and the vertical mouse helps me to keep that from becoming too painful.

The wireless connection for this mouse is excellent. It is very small - really just a nub that goes into a USB port. Since it doesn't stick out and doesn't connect to a wire of any kind, it's completely safe from my adorable but frustrating cat.

I highly recommend this mouse for anyone who has arthritis or repetitive motion injuries in their hands. I highly recommend the wireless version for anyone who needs to minimize wires for any reason.

I have been using this one for a while now and it feels better on my arm, I wish it would turn my wrist to a 90 degree to the table.the other thing I do now is instead of have the mouse at the end of the keyboard, I use it right about mid chest on the desk, big difference

I received this mouse on August 6th. When I received the product, part of the outer shell was misaligned and connected improperly (about an inch away from the "QC PASS" sticker mind you). I fixed this by unscrewing the case and popping the shell back into place. It was working adequately and comfortably until this morning on September 2nd, when the sensor appears to have stopped functioning and the mouse pointer no longer tracks its movement. This product is cheap plastic junk as far as I'm concerned.

Worked well for a few weeks, then the scroll wheel stopped working and the top "button" popped up out of the mouse (see pic). My return time period expired 10 days ago, so I cannot do anything about it!

UPDATED: TERRIBLE PRODUCT and TERRIBLE Customer Service! Scroll button totally stopped working after a few short weeks. Contacted seller. No response. Contacted Amazon who told me to send it back. URGH.I bought a right-handed version which looks identical to this a few years ago for $10. My right hand and arm hurting after 30 years of computer typing. So I got the left handed so I can keep working. Although I'm left-handed, I prefer mouse in right hand. Why? Keyboard shortcuts are on left side of keyboard. BUT I had to change, at least for now.It's fine, does what it's supposed to do. Now if I can only train my fingers to hit the correct buttons and to sit on the mouse. They want to dance around. Whereas on my right hand, my fingers stay where they should and always hit the correct key. Operator error.If you are looking for an affordable ergonomic mouse and are a southpaw like I, this is a great product. Even though it might take getting used to if you are a creature of mousing and keying habit like I.PS Good luck finding any ergonomic mouse, let alone for lefties, in any typical computer store. I went to a big electronics chain. They sell phones, TVs, computers, refrigerators and more. Hint hint. They wouldn't even let me try a keyboard or mouse. Gee, guess that big box store doesn't mind losing biz to Amazon, ya know? What's the point of going to a store if you have less options than Amazon, and can't open any boxes?Thank goodness for Amazon!!

had it for a week sent it back its so bulky and if your hand is constantly on the mouse like in gaming it is terrible FATIGUE

Wheel mouse broke after 3 months
