Summary: - I would not recommend buying this unless you absolutely must have something in this sort of vertical, ergonomic configuration. I don't know if something better exists for this purpose, but perhaps a trackball is the ticket. - I can't stress just how cheap the materials are on this product.
Pros: - I guess it's more comfortable on the wrist and hey, it's for lefties, which suits me. - Buttons are programmable, you can adjust the speed, etc. - The ergonomics seem well design to support your hand in the proper way (i.e. your finger won't drag across the mouse pad).
Cons: - Cheap, cheap, cheap, materials. The rubberized grip coating is wearing off and I barely use this thing. Seriously, I've probably used it for a total of about 20 hours since I've had it and the rubberized portion is becoming rough and brittle, wearing away. - Way overpriced.
Summary: I had been using a top of the line Logitech laser mouse for many years until my hand started cramping regularly and my wrist began aching. My wife loaned me her wired Evoluent mouse (VM2) and after a few weeks all of that pain went away.
Perhaps a mouse pad will work but I'm a minimalist and if there are other devices that work better for my setup I'll stick with

Summary: Overall this just didn't work for me. The thumb placement was too high compared to other vertical mouses, which didn't allow my wrist to naturally rest on the desk. Perhaps a mouse pad will work but I'm a minimalist and if there are other devices that work better for my setup I'll stick with it.
Summary: I have wrist pain. Even though I am seeing the doctor I wanted to give a try to this mouse. I regularly use a wireless HP mouse over a surface with a bit of a slope to reduce the tension on my wrist, that has helped a bit.
Summary: If you absolutely need an ergonomic mouse, this product is very usable. However, when I spend upwards of $80 on a mouse, I expect better quality tracking than you average $5, made in China, disposable piece of garbage.
Pros: This mouse is one of the few ergonomic 5 button mice with a scroll wheel. Well I guess its technically a 6 button mouse because the scroll wheel does not double as a middle mouse button. (Also an awesome feature)
Cons: This mouse has a serious tracking problem. Several times a day it starts to 'pull' all the way to the right edge of the screen. This continues until I move the mouse again. I suspect this issue is the result of poor quality firmware, possibly an overflow/underrun in the sensor data interpretation...
Excerpt: I bought this mouse because of pain I was having in my wrist. I have the small version because I have very small hands. In fairness, the wrist pain has improved but because the mouse raises my hand up, part of my hand (near the wrist) drags on the mouse pad and is a little sore and red.
Pros: This mouse is somewhat helpful for wrist aches, CTS. Laser movement is accurate. Many sub buttons can be used for macro assignments. Battery use is very good, like 5-6 months on one battery
Cons: Biggest complaint I have is the mouse wheel started to get flaky about 6 months into ownership. Scrolling down would occasionally go up instead of down. It's gotten progressively worse. I've made several attempts to contact the manufacturer for support and not received a single acknowledgement or...
Summary: 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.
Summary: I bought this mouse because I was having wrist pain / trouble and work on a computer all day. I was very impressed with the feel and the features until I noticed that it did not work on any surface other than a sheet of paper!
Summary: I wanted a good left handed mouse and this one is OK. Not great. Just OK. It feels a little cheap in the hand. The biggest fail is there are no drivers for MAC OS X. The manufacturers web site suggests you go to another site to purchase ($20.00) software that is not compatible with OS X Lion.
