Excerpt: I've been using this verticle mouse since 2002! I have mild carpel tunnel syndrome that affects the wrist! It can be painful but that pain and discomfort has been drastically reduced since using the Verticle Mouse! It may feel a little 'unnatural' at first but once you get used to it you won't want to go back to the 'flat' mouse! If you don't have any wrist problems, now is the best time to get a Verticle Mouse as a preventative measure!
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly
Summary: This worked out good for me keeping it vertical. One problem for me (minus one star) is that I have problems when I need to grab the mouse and move it. For example, typing on the keyboard and then coming back to the mouse. Inevitable I have to grab it and move the mouse and there isn't a good way to grab the mouse w/o hitting one of the buttons (e.g lower right button). They should have accounted for this in the design.
Excerpt: This is my second VerticalMouse by Evoluent..the first I had for 5 yrs+. I'm right-handed but my dr recommended I switch to a left-handed mouse but couldn't find one that was comfortable that wasn't causing cramping in my hand until I found this one. The way it keeps your hand in a vertical position and doesn't allow you grip the mouse solved all the issues. Very easy to use. Only issue is all the buttons it has. I'm a Mac user so don't necessarily need them.
Summary: This mouse is very nice for anyone who gets any sort of finger/wrist pains after prolonged usage of a mouse. The angle your hand sits at is much more natural than the usual mice, and takes a lot of stress off your wrist. The buttons are nice and responsive, but not quite as nice as my Razer Mamba.
Pros: - Vertical angle really decreases stress on the wrist, - Wrist pain is virtually gone after a week or so, - Speed controls and software definitely a plus, - Love the middle click button (and mouse wheel button can be set to anything you want), - Large mouse that fits nicely in the hand
Cons: - Still not quite the perfect shape, - Wrist hurts a tiny bit in a new spot now, - Takes some getting used to, especially in terms of how to grip it, - A bit too pricey
Completely helped my carpal and tendonitis; highest recommendation

Summary: I've been using the Evoluent VerticalMouse 4 for over 3 months now, and I can definitively say this the best purchase I've ever made for my ergonomic setup at work and at home. I was only in my mid-20s when carpal started to set in thanks to my career: eCommerce. I was on a computer all day at work, and had side-jobs and projects that kept me working while at home, too.
Summary: It takes a while to get used to, but works perfectly fine after the learning curve. The one thing about the design that I would change would be to add more lip at the bottom where the hand wraps around. This would make it so that the bottom of your hand could truly rest on the mouse and not have to suspend/flex your hand...for easier sliding...and would keep your hand from touching the cold table. BTW...I don't know if this is a bonus or flaw, but..
Summary: Evoluent has left some room for improvement to this mouse, but it is by far the best I've used. I've tried several pointing devices to relieve repetitive strain injury in my wrists and forearms, but haven't been satisfied with any of them. The Logitech Trackman Marble has a nice action and is good value, but the buttons are poorly placed and it lacks additional features.
Summary: I've bought lots of mice and other pointing devices and so far the Evoluent Vertical Mouse 4 is the best that I have. Pros: Keeps your arm and wrist in a more natural position reducing RSI Cons: This mouse is pretty vertical but not 90 degrees. Your hand is at an 80-85 degree angle and when you move your mouse sideways your wrist is at a slightly awkward position. If your hand is positioned at 90 degrees exactly, then it'll be much better.
