since I wasn't sure what shape would work better for me
April 15, 2017
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.
No more pain! No more problems! No expensive price!
March 11, 2017
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!
One of the best ergonomic mouse I have worked with ... (on budget)
October 9, 2016
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.
Magic Mouse For My Locking Thumb
July 28, 2016
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.
J-Tech vs Evoluent vs Sharkk vs Adesso
May 4, 2016
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.

A Critical Improvement for Me
September 29, 2017
If you have functional problems with your hands or fingers, this may be the mouse for you. I have both. I have had this mouse several days now, and it's been such a help. "Clicking" is a particular problem for me, and this mouse has reduced the need to click by about 75%. I set the mouse to click for me if I hover over a click spot. Also I was able to adjust how long the mouse needed to hover before the auto click function engaged, which I really need, as I have to have more time to get the cursor or arrow were I really want it to be. There are a lot of different things you can set the mouse to do for you, but I am not great with computers so there was some more complicated settings I don't feel comfortable doing. But the auto click, and the ability to move the cursor when typing by just hovering, is huge for me. I also set the "scroll" on the wheel to a faster pace so I have to move the wheel less. Also you can easily use different fingers when you do have to click, like your middle or ring finger, very helpful to me.If you understand programming better, I think there's a lot more you can do. This mouse is going to help me keep working, as my job requires a lot of computer work. I will be getting one for home as well. Size wise, I got the regular, I am not a large person, and the size fit fine. Thank-you to Evoluent for thinking about those of us with disabilities.
Reversed the pain of my carpal tunnel symptoms.
February 5, 2016
I've owned three generations of the VerticalMouse and they keep getting better. I have the original which I still use at home and a VerticalMouse 3 that I used at work. I've just purchased the 4 to replace the one I use at home, but not because it's worn out. They make these things to last forever, so it's still going strong, but the new one has a more contoured shaped that makes it even nicer to use.A while back I started to experience some significant carpal tunnel symptoms and having known others who had this, I decided to do everything I could to prevent it. After quite a bit of looking an testing out the various theories, I decided on the Evoluent for a mouse and the Microsoft Natural Ergonomic Keyboard 4000. It only took a short time for all of the symptoms to vanish. There was a bit of a learning curve where it didn't feel right, but it was worth it. It was either 'go ergo' or get a different job where I wasn't in front of computers all day.I've tried other ergonomic mice and been very disappointed, but I haven't tried many. This is because, when I bought my first one, they really had no competition and now, although I'm curious, they last so long that it doesn't seem reasonable to keep adding to the litter of mice on my shelf that I will never use.

January 19, 2016
I have been using this product for just about 1 year. I have had severe pain in the little finger of my right hand which also became cold to the touch - both of which I found was due to tapping the ENTER key on the numpad 10's of thousands of times over the years. I switched to this pointing device hoping it would relieve some of the pain as heavy computing is how I earn my paycheck. I am very pleased with this product as it has definitely reduced the pain in my hand and it also "fits" my hand... regular mice are too small and don't conform to ones hand properly causing the hand to curl entirely too much.I am even more pleased with the product since I've had a double click issue when single clicking which had been worsening over the past 2 months. I contacted Evoluent via email and a prompt email response from Evoluent technical representatives directed me to send in the unit and another prompt email was returned after they received the unit stating that unfortunately, they were not able to duplicate my concern, however they were sending a new replacement unit in its place. Wow. I did not expect that. At the very least, I expected to pay for a repair to replace a micro switch for the main left click. At most I expected to pay for a replacement unit.Excellent customer service and turnaround of about 1.5 weeks due to being located in the middle of the Pacific Ocean so shipping takes a bit longer.I've been using the replacement device for my normal heavy computing usage and have not had the double click issue.Thank you Evoluent for an outstanding experience. I've recommended the Evoluent product to my colleagues. I will purchase a wireless unit in the future.
I'll be comparing three mouses and there differences but first ...
December 26, 2015
I'll be comparing three mouses and there differences but first a short background for my reasons of needing an ergonomic mouse as we all have different reasons. I'm a gamer from way back in which to my knowledge caused to to gain carpal tunnel syndrome in which I had surgery over a decade ago actually I had it in both hands and both were operated on, years after the surgery, I still to this day have pain and discomfort when using a mouse. Lets start with the first mouse.I first purchased the Anker 2.4G Wireless Vertical Ergonomic Optical Mouse, July of 2014 in which alleviated or helped with the pain but still have some discomfort even though it positions your hand in an somewhat vertical position, it did OK but still left me in a bit of pain after long periods of use.I had just two weeks ago before Christmas bought and tried the Posturite Wireless Penguin Mouse though it positioned your hand in the correct position full vertical it was very cumbersome to maneuver the pointer, awkward as since your palm rest on the mouse it leaves you using you to use your whole fore arm to maneuver the mouse not near as accurate and precise as the Anker so I had no choice but to return it.I just purchased this Evoluent mouse and I have nothing but all positive to say about this mouse, hand position is the up right correct vertical position same as the Posturite mouse and more so than the the Anker mouse, maneuvering the pointer is spot on accurate, hand comfort with no pain and many more mouse buttons to offer so out of this group of 3 mouses the Evoluent is by far the top of them all in all areas.Edit In; 12/30/15I'd like to let known that I found the scroll wheel not working properly it would jump around in some applications not allowing the page to scroll, I contacted the manufacture and was instructed to uncheck accelerated scrolling box inside under the wheel tab in the mouse software for the mouse, by doing this resolved the problem with the scroll wheel not working.
Eliminated my repetitive motion wrist pains, used in all my mousing applications including PC gaming.
September 23, 2014
This is an evolutionary improvement over the Evoluent 3, which I used happily for several years [since Jan 2010] before the mouse wheel began to have intermittent failure to register movements. I find the changes made in shape not too problematic to adjust too, though I prefer to keep contact with the mouse pad using my smallest finger so the "shelf" to support it is unappreciated by me. Fine movements of the mouse are easier for me with that contact maintained. The additional button on the thumb side is appreciated.The software that can be downloaded to manage the mouse appears to work fine, though I miss the choice of "aero-mode" document flipping that I used to have available [maybe that is a Win 7 operating system issue, I'm not sure], Also, the middle mouse button appears to be recognized differently by my game software, I don't understand why : I had to assign MB6 to it's function in Elder Scrolls Online. I had no such problems with mouse button recognition using the Logitech G5 (my previous and still back-up mouse)I originally purchased this mouse to relieve repetitive motion pain symptoms in the right wrist when using the computer for extended periods of time. It completely resolved the pains. After using a regular mouse for several days when the mouse wheel began to malfunction, I could feel the wrist symptoms returning. As of now the symptoms have again resolved, and did so immediately when switching back to the Evoluent VerticalMouse 4.I should mention that the switches used on the mouse are responsive and seem to work a little better with the upgraded device. I actually use the mouse for gaming, these things are important to me. An all-in-all sound investment, one I would be in real trouble without having made. I have never tried other brands of "vertical" mouse products, and the reviews of them don't encourage me too change. This was my first and remains my only choice for ergonomic computer mouse.
What elbow pain...?
October 19, 2011
If you are a graphic designer, just stop reading and buy this mouse. The idea behind it is brilliant and since you are a designer, you hugely appreciate brilliance when you experience it. After a short while, your wrist, elbow, and sometimes shoulder pain will be gone, as will the hideous browsing-bump on the heel of your hand that grows in direct proportion to your mouse-time.Believe it or not, the evoluent software is actually great. I thought the idea of an automated alarm telling you to stretch for 1 minute and then telling you to get back to work would drive me crazy, but the opposite is true. I stretch and then drop down and rap out 25 push-ups and it's better than a cup of coffee.A couple musings:You WILL get told by people who see it (guys) and try it out that it feels like holding a hard-plastic breast. It will then be impossible to remove this analogy from your thought processes.If you run Windows 7, do not EVER customize your taskbar setting to hide the icon for the evoluent software. I made this mistake and there is no correcting it without a clean install of Windows 7. A registry bug that is virtually unfindable results from doing this, and no amount of uninstall and reinstall will correct it.There is an awesome button you will love that allows you to switch to an excruciatingly precise cursor speed, which is greatly helpful in the design world.Two enthusiastic thumbs up.

Good quality and works as designed
June 10, 2017
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.
Probably best ergonomic mouse out there with a [fixable] flaw. 10 MONTH UPDATE: two fixable flaws
March 5, 2016
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 ...
Feels good in the hand but one glaring problem
January 15, 2016
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.
Orientation should be rotated 45 degrees. Anyone know how to do that?
September 13, 2015
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.
Best vertical mouse at the moment!
March 24, 2015
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!

Comfortable device
March 12, 2017
I've been having issues with both my wrist and elbow for the last few years - not all started from using a computer daily. However, they would become aggravated with continual computer use. At times, this would require minimizing and avoiding the mouse as much as possible - not a big positive when my work requires it. I had been doing much better until recently. Due to this, I began researching alternative's to the standard mouse. After reading all the reviews, I ordered the Evoluent VerticalMouse.I am happy to report that after months of use, the elbow issue has become almost non-existent. My wrist and hand issues have also become much better. However, while it has greatly improved the ulnar and median portions of my right wrist/hand, most of my issue has been at the base of the thumb (radial) and index finger back into the outside of the wrist. While the mouse does an excellent job maintain a better hand position for most issues related to pronation, it does still require a 'pincing' motion between the thumb and index finger. Again - it is a major improvement over other devices and has greatly increased my comfort; however, if this area is your primary problem, just recognize this mouse is not the panacea for all hand/wrist problems.I still recommend this mouse highly as it has been a major improvement for me. I would just recommend maintaining your expectations.
Good but expensive
February 22, 2017
A good product, if expensive. It's a specialty product that's probably not produced in huge numbers like your typical $20 Logitech mouse, so it's got a higher price. The silver on the thumb rest feels like the plastic you find on cheap Chinese toys. Doesn't feel like it should cost $80 - $90 new, but that's the way of things. The Kinesis Advantage keyboard feels like a hollow bathtub toy and it's $250 - $300, but it's a similar niche product. The buttons and thumb rest attract skin grease like a magnet, so you'll probably want to scrub every once in a while.The software that comes with this is junk if you want to click and use the keyboard at the same time, at least under Windows 10. When I held down a key on the keyboard and tried to click on something, the click didn't go through. I first noticed it while trying to play a game, but it happens in productivity software too. I uninstalled the Evoluent software and switched to "X-Mouse Button Control" from highrez.co.uk to re-assign my buttons and never had that problem again.A useful tip to turn off that obnoxious light on the back: make sure the computer is on, unplug the mouse, hold down the pointer speed "-" button on the side of the mouse and plug it in. No more light. It still shows the little green lights on the top to indicate the speed/sensitivity.As a mouse it is good. Optical mouse, adjustable sensitivity, upright stance, puts the mouse cursor where you want it. It has outlasted the Anker wireless vertical mouse I bought around the same time whose scroll wheel has started becoming unresponsive. A bit expensive, but I'm hoping this and my trusty Microsoft 4000 keyboards will fend off carpal tunnel / RSI a bit.
Great design, great for Windows - no Sierra drivers at this writing
November 17, 2016
I've been dealing with tennis elbow for the last year and a half. I was forced to stop working out in the mornings until it healed. Even after months of inactivity, however, I was still have issues with my elbow. After doing a little research, I discover a related condition I'd never heard of before - mouse elbow. Because of the nature of my work, I'm mousing all day long. I concluded that pronating my hand all day, was contributing to my tennis elbow, and lack of healing. I needed a solution. After reading the reviews, I decided to give this mouse a try. I purchased it and set it up at work. I can honestly say, in the thirty plus years I have been using mice, this is the most comfortable mouse I have ever used. It took very little effort to get used to it. It keeps the hand in a natural "hand shake" position, and once I'd adjusted the speed and tracking, I found it took very little movement at the wrist, to manipulate my cursor across the span of my two screens at work. I was so pleased with it, I purchased a second one to use at home, which brings me to why I gave it four stars instead of five.At work I use Windows 7. At home, I was using Mac 10.11 (El Capitan). The mouse worked fine at first. Once I upgraded to Sierra, however, the mouse became a door stop. Nothing functioned as it was supposed to. Most of the buttons were dead, or stuck in one function. Yes, I know. My fault. I wasn't paying attention. I wrote to customer support about the problem. They responded that new drivers with Sierra support were on the way, and should be issued in about a week. That was three weeks ago and still no updated drivers.To be fair to the company I should have waited to upgrade the OS if I wanted to keep a functioning mouse. And, this isn't the only company whose product has had issues running with Sierra. It begs the question, however, with Sierra having been months in beta, so companies like Evoluent could write drivers before the official release, why do these companies wait until after the official release to suddenly discover their product doesn't work? Why make your customers wait weeks, sometimes months, after an official release to START working on the driver problem.In conclusion, the product gets four stars for great construction, and if you run Windows, great drivers that let you configure the crap out of this thing. One star gets deducted for poor preparation for the Mac Sierra release. At home, and until the updated drivers are release, the mouse is little more than a door stop.
Expensive and initially gaudy, but a true vertical mouse.
January 21, 2016
I have the wired version because I read all the negative reviews of the wireless / bluetooth version. Purchased Jan 2016.Pros: Does what it says on the tin. It's a vertical mouse.Cons: I had an earlier version of an Evoluent and it was much less gaudy and it was easier to setup on osx.- Bright blue light on the back of the mouse is pointless, distracting, and burns battery power even when the laptop is closed. I'm generally opposed to blue LEDs but this one is particularly distracting and serves no value. This is my only major complaint.- The driver software allows you to select actions to assign to all the extra buttons, but they don't allow you to actually customize. I'd like to have the 5/6 buttons near the thumb select next or previous tab on my browser, but that's not an option they thought to put in the dropdown, so I'm out of luck. I'd also like to switch spaces with a chorded press (6+2 or something) but it requires changing the keyboard shortcuts to the osx default settings. The Anker mouse does not have this restriction, it allows you to record whatever keypresses you'd like to attach to the extra buttons.- Drivers: On my MacBook, running OSX 10.11, the driver install is required to get functionality out of buttons other than the basic two, and the driver install requires a 1999 style reboot of the whole computer. For a mouse, this is excessive.- The website has irritating autoplaying video, which isn't great for downloading the drivers in an office environment without being distracting to others. The direct download for the osx drivers is here: [...]Update (May 2016):After about 4 month of use, one of the thumb buttons failed. I believe the failure was a component failure, not a design failure. Regardless, Evoluent was very helpful to send me a replacement under warranty. While they had my mouse, they noticed I'd taped over the blue light, which is my biggest complaint. Here is part of the email they sent as a reply:If you don't like logo, you can turn it off.Logo off :Unplug the VM4, press and hold down "-" pointer speed switch, plug in themouse and release the pointer speed "-" switch.Logo on:Unplug the VM4, press and hold down "+" pointer speed switch, plug in themouse and release the pointer speed "+" switch.
Good for wrist, terrible finish/coating.
April 22, 2015
This really helps with carpal tunnel and wrist pain.The finish is terrible. It gets soft just from your hand oils and starts rubbing off after a year or so. I saw another review that said that alcohol would dissolve the finish, so after it started coming off, I used some alcohol on purpose to remove all the loose finish. The slick plastic that is under it actually feels nicer to me than the original finish. I don't know why they felt the need to use such a terrible coating. It's not like there aren't finishes out there that can be in contact with hand oils and not dissolve.
The mouse feels great, but I was unable to use it right ...
August 8, 2014
So I originally bought this mouse because I was having tendinitis problems in my arms and needed to change the way my arm was resting on the desk etc. The mouse feels great, but I was unable to use it right off the bat because unlike a normal mouse, you kind of have to grip this one with a bit more force when clicking, otherwise you'll push it off of your pointer target. The extra gripping for sideways clicks didn't help the tendinitis, so I am saving this mouse for once I'm healed.Otherwise, quite comfortable! Took me less than an hour to get good at clicking without having the mouse pointer move off my target =)

Not good for gaming
September 5, 2017
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.
Some days I could throw it through the window
July 23, 2017
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.
First mouse defective, quick customer service reaction, sent second mouse, still now wowed by the design.
May 12, 2017
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.
Too small for me.
March 24, 2017
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.
As Novosib said, GREAT mouse (with one flaw for some of us -- but easily fixable)
August 13, 2016
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!

ergonomic, yes, but cheap and flimsy
January 3, 2017
I switched from a Razer Mamba 2012 to this mouse about two years ago. The vertical design definitely helps with wrist strain when mousing for more than a couple of hours. I use a computer 12+ hours a day, so that's important. It's also nice to have a dedicated middle button instead of having to click the wheel. Unfortunately, while the VerticalMouse is a decent step up in wrist comfort from the similarly-priced Razer, it's a huge step down in build quality and durability.The VerticalMouse has a cheap, plastic-y feel that would be acceptable from its $20 competition, but not from a $80+ device. The finger contact surfaces are made of smooth, shiny plastic that makes my fingers sweat and needs to be cleaned frequently. Worse, after about a year my skin oils started eating away the matte coating on the palm area. Worse still, here at the two-year mark mine is starting to break down. The debouncing on the left button is failing, so about half the time single-clicks get turned into double-clicks. Sometimes it just shuts off entirely and needs to be unplugged to reset.I also suspect it doesn't really fit my hand properly. I have rather large hands, and with the regular VerticalMouse my little finger either rests on the table or feels squashed if I keep it on the mouse. It would be nice if there was a large model in addition to the current small and regular.In short, this was a decent mouse for a couple of years, but now it's failing and I'm not going to buy another one. I'll go back to the Razer (which is still like new after being used for three years) while I research other ergonomic mice to try.

October 30, 2016
I liked the idea of the vertical mouse having a natural hand position, but I found the reality was not what I expected. The mouse feels large and because you put your hand in a vertical position, you have to "squeeze" the mouse to keep your hand in place and move it around. It was awkward and tiresome to use.
Updated: Good for Light Mousing, Problematic Pinch Grip
January 7, 2014
I have used a 3M Joystick (Renaissance) mouse for several years, a good design that has really helped with carpal tunnel syndrome. I like the 3M's rocker switch, vertical orientation, hand support, and fairly fine degree of control. However, it has two issues: the narrow column of the joystick requires a good grip, and the raised baseplate can press on the wrist. So, I decided to try out the Evoluent as another option in my RSI mouse parade, to even out some of the stresses.Being focused on the fact that the mouse is vertical, I didn't pay too much attention to the mappable button feature on ordering - but I'm now finding this is a great strength of the design, as you can map the buttons to those fingers that have the most control or are least affected by RSI.My one initial concern was that the required "pinch" grip might add stress, as it is also somewhat slippery.Two nits: Don't need the lighted blue logo at the base -- a waste of energy and too bright; and the USB cord is very long for something that sits right next to your computer. This cord should at least be removable from the base of the mouse, so one can switch in a shorter cord.Overall, this seems a well made product and is definitely of value to people not only with RSI but various hand problems who need something that is larger and easier to grasp than the typical mouse, and with buttons in a variety of locations that can be mapped to work with their strongest fingers or deal with tremor/spasticity.**Update: To keep the hand-wrist-arm in a "straight line" position to not bring on numbness does require having some type of pad (like a gel wrist rest) to support the lower arm.**Update 2: Something to watch out for if you do a lot of mousing. I used this mouse only in the evenings for light computer work/gaming for a couple of years. Then, I switched last summer to using it as my main work mouse (8 hrs+ a day). Unfortunately, this extended time using the "pinch grip" required to hold the mouse quickly brought on De Quervain's - inflammation of the tendons of the thumb. It is now sometimes quite agonizing to hold the mouse and draw it back. I hate to give these mice up but I'm going to try switching to a different design for awhile that doesn't require a grip, and see if I can eventually go back to using this as a "light duty" mouse.
No Windows 8 drivers as of July 2, 2013
July 2, 2013
This is a great mouse. The "handshake" position is much more comfortable over long periods than the palm-down position -- at least for me.Unfortunately, as of July 02, 2013, there are no Windows 8 drivers available. Do not install the existing Evoluent drivers under Windows 8. The mouse will not work at all.The only driver that works is the generic Microsoft mouse driver. In this configuration, the mouse buttons are not programmable. I like to program a dedicated mouse button to generate a double click with one physical click. Rapid double-clicking causes me hand strain. No dice without drivers.Evoluent support says that the company will write drivers but they don't know when. The lack of drivers is forcing me to consider going back to a palm-down mouse.If Windows 8 drivers existed, I would give the product 5 stars. Until/unless that happens, 3 stars.
Helps ease wrist/arm/shoulder pain, but quirky
April 11, 2013
I have owned the Evoluent Vertical MOuse 4 Right for about 2-1/2 years now.The good: Really does ease wrist/arm/shoulder pain when using for long periods compared to standard optical mouse. Nice feel, fits my hand well.The bad: Has electrical/mechanical quirks. Explanation:After about one year with the mouse, the cursor started jumping around on the screen as I was using the mouse. It was very erratic, and very frustrating.The mouse would occasionally freeze up completely, and the blue logo would go out, indicating a loss of USB power. The only solution to this problem was to reboot the computer.The frequency of the problems began to increase to a point where I could not use the mouse.In order to eliminate the possibility that the problem was the OS (Windows 7, 32-bit), or the computer, I performed the following tests:1) Used the mouse on Ubuntu Linux which was installed on the same computer (dual-boot). The problem persisted.2) Eventually I had to replace the motherboard in this computer (for reasons other than the mouse). When I started using the mouse on the new system, which now has Windows 7 64-bit installed, the problems persisted. Again I also tried the mouse in Ubuntu Linux and the problem persisted.3) Used another mouse on the same USB port. No problems with the other mouse.Eventually, I contacted Evoluent support and, after several e-mails between us they decided to replace my mouse, even though it was out of warranty. I had to cut off the cord on the old mouse and send them a photo of it to prove that the old mouse was unusable. I received the new mouse in a few days.Well, the results are in, and I am still not a happy mouser.The erratic cursor movement is gone, but now I have another problem. The left-click does not always take. In other words, I click the left mouse button, but Windows does not respond, and I have to click it again. This happens quite often, in many applications, but especially when clicking buttons on web pages or applications.Swapping the right and left mouse buttons does not seem to fix the problem. That leads me to think the problem is either with Windows or in the mouse's interface (driver or hardware).If I hold the mouse button down for a longer period (which is far longer than is normal), the problem lessens, but does not go away completely.I have tried using the mouse with both the default Windows driver, and the Evoluent driver with the same results.I have not yet tried the Evoluent mouse on another computer (I don't have another computer that is usable for most of my applications), but I have connected another mouse (actually a trackball) to the computer, and have not had any of the problems with the trackball.I suspect that the trouble is with the hardware inside the mouse. It is not the actual mouse button, but the electronics that reads and processes all of the mouse buttons and sends the data along the USB cable to the computer's USB port.I ran a utility that tests the mouse buttons, and found that occasionally when I click the left mouse button, I get a double-click instead. I don't think that would cause the failure to register a left-click (double-click will normally do the same thing as a single click for buttons on a website or in applications), so I really don't know what to think.I will not try another Evoluent product, as I believe that, considering my problems with not one, but two of the same model mouse, they are having design problems. Perhaps they will come out with a Vertical Mouse 5, and I can convince Evoluent that they should give me a beta version of the new product for testing (well, I can dream, can't I?).I am pretty much at the end of my rope for dealing with this mouse. I am probably going to purchase a new gaming type mouse to replace the Evoluent. While the gaming mouse will not be as easy on my biomechanics, at least it will ease my mind when it works properly every time.At this point, I do not recommend this product.
Not horrible, not great...2.5 stars rounded up...
March 7, 2012
Just a quick video review of the Evoluent Mouse. I discuss some pluses, some minuses and my overall impression of how it works for me.A point I don't clarify in the video is when my hand feels good (nerve problems aren't flaring), I still prefer to use a normal mouse over this. It's just easier to work with. I'm also ambidextrous a bit, so with a normal mouse, I can use either hand if need be. This mouse is only good for my slightly-dominant, right hand.Finally $89 (or something near there) is a LOT to pay for a mouse that doesn't entirely fit the bill. It would be a real coin flip whether I would buy it again (for that much money anyway) now that I've worked with it a bit, and I'm not so blown away by it.

Scroll Wheel Does Not Work Well
April 12, 2017
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.
Hard to move and difficult to achieve precision
March 22, 2017
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.
Nice Concept and Shape, but a poor quality mouse.
September 12, 2016
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.
Not quite an ergonomic mouse
December 16, 2015
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.
- Light

Cons:
- 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.
"wonderful" until it wasn't!
May 18, 2015
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.

Disappointing
June 7, 2015
Overall I've had a poor experience with this. The upside is it does help me use the mouse a lot longer without suffering RSI related issues. The pitfalls are too much to overcome, unfortunately.As other reviews mention, this mouse has a problem with missing clicks. I've tested it and it happens on average of once every 30-50 clicks, where a click will not register. This makes working on the PC very frustrating as you end up waiting for an action to happen only to find out it didn't because the mouse ignored your click.It also has a problem where it will act like the button that has been clicked and released is instead still being held down. This has occurred with both the left and right buttons, and occurs for about 1-3 seconds after the button has been released. Occasionally the mouse will simply stop responding completely and the only way to resolve it is to go to the back of the PC and physically unplug the cable and replug it back in.I have attempted everything I can think of to eliminate these problems with zero success. I updated to the latest evoluent drivers. I uninstalled their mouse manager utility. I changed usb ports on the back of the PC multiple times. I even tried completely uninstalling their drivers in case it was a driver bug. The problems persist regardless.The navigation back and front buttons are by default mapped non intuitively and the only way to resolve this is installing their mouse manager software to remap the buttons. The rubber grip on the mouse began flaking off after only a few months of use. The USB cable is extremely thin and flimsy and makes me suspect the clicking problems might arise from poor usb signal integrity. The build quality falls far short of what's expected for the money paid.In summary, what was supposed to make my mousing experience less frustrating and fatiguing has in fact had the opposite effect. I have RMAd this back to the manufacturer, and will see how things go from here.
Over priced and under delivers
February 6, 2015
This mouse is most definitely not worth the money that they are asking for it. It may work for other people, but all it did for me was to take my wrist pain and rotate it slightly to a different part of my wrist.Let me be clear and state that this is not a 'Vertical' mouse. It is close, but definitely still at an angle, albeit a steep one.*UPDATE - 6/22/2016*I just got back from vacation and after taking a week off and not touching a computer mouse or keyboard for the duration, my wrists felt great! Until I started using this mouse again... I've been using it as my primary mouse at work for the last 2 years (or so) and I thought I was doing alright even with my negative feelings towards the mouse and the constant slight pain when using the mouse, but now having spent a bunch of time away from a computer, I can very definitively state that I have a used VerticalMouse 4 for sale.With all the time I've spent with this mouse, I want to like it, I really do, but I just can't in good feeling recommend this mouse. I haven't had any of the cosmetic issues some other people report and even though it does feel like cheap plastic, it has lasted through 2 years of consistent 40-hour work weeks.The thing that bugs me the most, and I thought I could get used to, is the funky angle of this mouse. Its not vertical (as I stated in the original review), its slightly off. They state that the mouse is designed to be a comfortable 'hand shake' grip, but who shakes with their palm down?Imagine this: reach out your mouse hand for a hand shake (my palm is ever so slightly facing upward) and then, without changing how your hand is held out, rotate your wrist to where your palm is vertically straight (if you are right handed, this rotation is counterclockwise). Pause for a second and enjoy the vertical feeling. Now rotate your palm further another awkward 30ish degrees and that is where the mouse will hold your hand. Not a comfortable position for me.Why did I stick with it for two years? I'm the kind of person that when I spend a large sum of money on the 'truly ergonomic mouse' I want to believe that it will be good for my wrist, but, as many other suckers can tell you, just because you spend a lot of money on a product doesn't mean that it is good for you.
Just plain "meh" and definitely not worth $90
January 25, 2015
After seeing all the glowing reviews that mentioned "immediate relief", I was hoping to experience the same. Unfortunately for a number of reasons I was left disappointed and will be returning this mouse. Specifically,- Buttons are extremely sensitive...EXTREMELY. The lightest touch sends them clicking away, dragging and dropping bookmarks, folders, files, and anything else you really didnt want relocated, cut, copied, pasted, and generally FUBAR- Size is big but not big enough for anyone with large hands. I'm 6'5, have proportionally sized hands, and found myself having to perform finger yoga any time I wanted to use the scroll wheel- Quality of build is cheap and lacking. The mouse is VERY light weight, feels cheap, and the slippery plastic buttons get an oily, dirty feel almost immediately.- Drivers & Software have potential but just don't function correctly. This could very well be local settings, other drivers, and anything else related to my machine. I was simply trying to deactivate the right mouse button (see hyperactive click sensitivity above), but despite re-installing this drive, uninstalling all other mouse software, and trying repeatedly, the right mouse button still fired awayThis mouse is basically a great idea not done correctly
OverPriced, Primitive Software, Poor Ergonomics
October 6, 2014
Summary: Better products available at a fraction of the cost. The driver software is primitive compared to what is available today at much lower cost. The mouse was first released years ago. My guess is that the company has been milking a cash cow without updating their product.Ergonomics:Not every hand and arm is the same so there is no "right" ergonomic design. But I've been very comfortable with other so-called Vertical mice but they supported approx. a 60 degree angle of the hand and forearm. The Evoluent design wants the hand at nearly 90 degrees. After trying the mouse for several weeks that angle still feels too extreme and I use the mouse with half my hand in the air so I can get to a comfortable angle.Not enough room for little finger. When using the mouse as designed my little finger would often go numb.Driver Software: Software is the secret of any mouse with more than the 5 buttons that Microsoft supports. Mouse software designed for gaming supports as many as 11 buttons where every button can be customized to do anything including running a macro that executes several clicks and/or keyboard keys.Macros: I couldn't get them to work. There is a primitive "Keystroke Recording" setting with the Evoluent mouse driver but I couldn't get it to work. In general Evoluent's software is downright primitive next to those offered with gaming mice which are often sold at a fraction of the cost.The mouse driver is advertised to be customizable for different programs. The claim is only partly true. Not all features can be customized differently to work with different programs. The scroll wheel can be set to scroll up or down but only one setting is allowed. The very first feature I tried to customize with the mouse was to scroll 1 line with editors but scroll several lines when using a web browser; that is impossible with the Evoluent mouse.
Not beneficial to me
July 8, 2014
I work on a computer all day long and often into the evening. The keyboard doesn't really give me any problems but the mouse sure does; I get a lot of pain in the forearm. I had hopes this would help but it really didn't seem to have any impact. I gave this several months of steady use and didn't see any difference in pain. I ended up going back to my old solution of alternating hands and giving one hand a rest until the other starts hurting.I find it hard to tell which button the main fingers are on; there really needs to be more definition to the left/right/mid buttons so finger placement is known at all times. This mouse could go a long way toward being more form-fitting to the hand. The cord seems quite fragile, and it is not easy to position the mouse to keep it out of the way. Like others have mentioned, it is a magnet for finger grime and has to be cleaned often. I did not have the problem some others reported of not being able to move the mouse around; I quickly adjusted to tilting the mouse to the right so it did not track and then it is very easy to move to a new location.This mouse does have some nice features like extra buttons for the thumb and easy DPI switching, so I gave it 2 stars instead of 1. The software is not very high quality, and the tray icon serves no real purpose except to display the DPI setting. Unfortunately the mouse did not help with what was 100% of the reason for my purchase, so considering the cost and the problems it's a 2 for me. I no longer use it and one of these days it will probably show up on the shelf at the local Salvation Army.
Not happy at all..........

I ordered this product because I have very large hands and get cramps "clinching" normal mice. This unit was not nearly large enough for my hands but what bothered me mostly was the quality of the product. I have been around/working with computers for over 30years and have had many many mice and know quality from junk. While this mouse was not bottom junk it was definitely on the cheap side. It was so cheap that the wheel clicks were off and it didn't register a "click" until you rolled it through two to three clicks when rolling down. Rolling up worked ok so this was not a software issue. It was clear it was hardware and this mouse felt to me like cheap, made in China junk with very low quality control. I would expect this gladly if it were a $20 mouse but for the price of this thing? I don't think so. On a positive note the design is interesting and I can see would help carpal tunnel, but only if you have smaller hands than me and if you got lucky and got a good copy.

a few design issues caused me to return it
April 25, 2017
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 and heavy lots of surface drag caused excessive wrist pressure to use all day.
October 13, 2016
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.
Nice idea, driver issues render this unusable
February 2, 2016
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.
Lasted less than a year.
December 11, 2015
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.
Loved it right up to the moment it died

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.

... that both VerticalMouse 2 and VerticalMouse 3 have worked great on previously
July 11, 2017
Mouse pointer is lagging / jumping across the screen when using it on the same desktop surface that both VerticalMouse 2 and VerticalMouse 3 have worked great on previously. The technical quality has really decreased in this new revision, and the premium price of the product is no longer justified.
looks like an expensive mistake
May 17, 2017
bought in Feb 17. started scrolling by itself today 5/17. now left button does not work. so now I have and underweight paperweight.Return window ran out 3/22.I have purchased 2 of these. 1 for work and 1 for home.looks like an expensive mistake.
Failed after 1 year
October 20, 2015
It would be great if it were built to last. After 1 year the left-click button began to treat single-clicks as double-clicks most of the time. I received a replacement mouse under the warranty. Unfortunately, after a bit more than 2 years the replacement has failed in the same way. Now looking for an alternative that is made with quality construction.
Buttons Do Not Always Work
January 22, 2015
The buttons on this mouse do not always work. Sometimes the click is not registered and sometimes it is registered as a double-click. This is the second time that I will have to return this mouse for the same problem.
Should have listened
September 9, 2014
Got the mouse yesterday. Feels nice in the hand but I'm having the same problem as many of the complaints I'd read before purchase: the left button is intermittent. Most of the time it works but probably 10 times yesterday afternoon, and already a handful this morning, there is no response until you hit it a second time.
Got Bad Unit and Learned about Poor Customer Service
March 13, 2013
I was mostly happy with this product after receiving it. Unfortunately, it soon began to simply stop working every few hours or so. Sometimes the light would go out and I would need to replug the USB cord, other times the light would stay lit and I would need to jiggle the unit for a few seconds to get the cursor to work again. I was unsuccessful at finding a customer service telephone number so email the company instead. It's been four business days since and they still haven't resolved my issue or even responded with how they plan to address it. Moreover, they insist that technical support is by email only. Of course, this is greatly prolonging my ability to have this problem resolved. In the mean time, I have a mouse that occasionally just doesn't work.
