EvoluentVertical Mouse 4 Right Hand (VM4R) - Ergonomic USB Wired Mouse for Laptop and PC with Jestik Microfiber Cloth (Regular Size) Black

I specifically searched for a different style of mouse to combat tendonitis developing in my index finger due to excessive daily mouse clicking on my job. I bought this and the Zero Tension mouse, this one has been much easier on my pain and less aggravating of the symptoms. And it feels much more comfortable so I took this one to work and brought the other back home. I even started using it with my left hand until I can give my right more rest and time to heal with rest, ice and anti-inflammatories. It is very comfortable to the hand and fingers. And although I agree w/another rater, sometimes it doesn't seem to click as it should (i found out there is a blind spot/area where it just doesn't catch -it all about finger position) nevertheless, for now and my needs, this is the best mouse ever! It did take some desk/keyboard respositioning as well and a little getting used to. but way less of than what I went through with the zero tension which is kind of awkward on the wrist if you don't have long fingers. I like them both and maybe if my finger wasn't so inflammed, the Zero Tension would be better, but for now and for my situation this one is the best!

This is the second Evoluent mouse I got and it works great. It is ergonomic, easy to use and very comfortable. I highly recommend it.

best thing I bought on Amazon so far! it really made a difference in my dealy computer life.it takes time to adjust and use the vertical mouse to your advantage. Still, you'll see the results soon enough.great size, fit, quality. and it looks fabulous on your desk ))

This mouse feels great on the hand. Very smooth and easy to navigate. Can Program it whatever you need. Thumb buttons are a bit awkward and the packaging is not worth the cost of the mouse. Thats why the 4 stars. Overall a great mouse so far.

I am a Realtor so I am on my computer a lot. I had a computer engineer come look at my computer and he said I needed to get an ergonomic keyboard, stand up mouse and put my lap top up on a stand at eye level. I went on Amazon that day and ordered all his suggestions. Made a huge difference with my wrist fatigue and I don't get headaches from looking down at my laptop (due to the stand). If your going to do one best to do them all.When folks come into my office they always comment on the mouse as many have not seen one ever. They all love it.

Appears to the a previous return as the package was partially open when I received it. Buttons didn’t work correctly even after I changed the custom settings. Will not order this brand again. Frustrated.

I could not use a regular mouse anymore because of the pain in my wrist. Once I started using the Evoluent I noticed an immediate cessation of pain in my wrist. I've used the mouse for a couple of months now and its made a huge difference. I don't have to wear a brace on my wrist and its easy to use. I thought it might be difficult to adapt to the new shape and motion of the mouse but its actually quite intuitive and now I think its feels much more natural than the flat mouse.

Once my doctor told me I had tendonitis in my right arm, I had my work space evaluated for ergonomic improvements. It was suggested I change to a vertical mouse. It was a little strange at first, had to get used to the hand placement. But once I did, I love it! It puts my hand in its natural position. I'm at the computer all day so this really help. I just plugged it in and it was off to the races. I would recommend this mouse to anyone.

There's definitely an adjustment period, but if you're looking for an *ergonomic* solution to wrist issues, this thing's worth consideration. I find it really intuitive for left/right movements, but forward/back (up/down) feel less coordinated to me, I think just because I don't have muscle memory with my wrist in this position yet. Trying to digitally sign my name for example is MUCH easier with a traditional mouse, but at worst the vertical mouse is 'a bit less coordinated' and at best it's a massive panacea for RSI sufferers, so I'll take it. :)The mouse itself is nicely built, though I'd have liked it to be heavier I think...it feels a bit more plastic-y than I thought it would, but still reliable.

Works well, stands up to abuse. I have purchased many of these for work. They have lasted for years with minimal problems.

has really helped with my wrist/arm pain.
