Summary: While this is a great improvement over a basic mouse and would be good for people who have no elbow support while using the computer it is not for me as my desk is U shaped and my arms are supported to take pressure off my shoulders. The vertical arrangement causes a shift muscles in my arm that are used .. aka ones that haven't been used in a while complained .. also my pinky finger will have to develop new callouses and felt cramped.
Pros: Great improvement over basic mouse, Light touch buttons
Cons: Not a improvement over a gaming mouse, 90 degree rotation of muscular control of mouse movements
Summary: 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.
It is ..... better than a typical flat mouse but.....

Summary: The Evoluent is much better than a typical flat mouse but A) wish it were a tad bigger for my hand. B) Wish it was tilted a bit more to the left. I find I still ungrasp the mouse and tilt my resting hand further to the left (ie, more like a true left handed hand shake would be if we shook with the left hand...) and C) The mouse has a tendency to freeze when videos (ie YouTube, et al) are playing some videos. Not all, but those with a lot of action and or high volume.
Summary: UPDATE, 6/12/2013: I've kept the mouse for months now, using it every day. I'm better at navigating it, but it still takes more care and concentration than a regular mouse to avoid moving things by mistake or to the wrong folder. Another issue has come up: If I use it too long I start to get an ache in my shoulder, partly, I suspect, because of the extra tension exerted to control this properly.
Summary: I've purchased four of these mice just over a year ago for my brother and I to use at work and home. We love them and don't like using other types of mice, but we have noticed a couple of flaws to them: 1) The rubberized finish on the palm grip section will wear off where your hand contacts it, particularly if your hands sweat while using it. This ends up making it look ugly when it starts to look patchy, and feels uncomfortable under your hand.
Pros: >Vertical grip very ergonomic, reduces strain due to extended mouse use, >Custom button mapping can be tied to specific programs, >Very light, glides effortlessly, >On the fly sensitivity adjustment is useful, >2 year warranty useful, especially since the cons will show up after about a year.
Cons: >Expensive, >Rubberized finish deteriorates and comes off, particularly if your hands sweat while using it., >No strain relief on the cord, so it will break if you're not careful to avoid it bending at extreme angles., >Buttons may wear out and the clicks won't register as cleanly as they should., >Smooth plastic finish of the buttons seems to attract grime
Excerpt: I have a wowpen that I didn't like when I first got it, because it was heavier than my other mouse, and I don't like it that it doesn't have a lip at the bottom outside for my pinky. Plus, it's super hard to click.<br /><br />But I got it out again recently when my light, regular, 3-button mouse gave out on me, and, after using it for a few days, noticed that some shoulder pain that I've had for years was going away. And away it went. It's not there.
Pros: Durable, Easy To Configure, Lightweight, Quiet, Versatile
Summary: I've had it for about 2 weeks and I've got mixed feelings. I'm a right handed s/w developer, and had to switch to a left mouse 10+ years ago, so I'm an experienced left handed mouse user. This is my first 'lefty' mouse, I'm just used ambidextrous ones and trackpads till now. Pros: - it's different. Since I use computers at work and at home, and laptops and desktops, having a different mouse is important so that no one part of your wrist gets overused.
Excerpt: On first plugging into my intel iMac, it would not work, then searching the Evoluent website, i found that they agreed and recommended two software plug in. The first- overdrive- caused the mac to seize up, uninstalling the software was a pain. The second, 'Steermouse' works, although I still have not been able to programme the buttons as I would like.It's working fine now ( I'm left handed- difficult to find suitable mice).
Pros: Accurate Tracking, Comfortable Design, Fast Response
Cons: Can't use all buttons, Expensive, No software for iMac
