Ergoguys Ergonomic Rockstick 2 Meduim Mouse Wireless KOV-RS200WM, Black

I love the design and comfort of this mouse, however, after only a few days of using it would short out and it completely died within a month. The battery dies constantly and you will always be changing it. It completely stopped responding after a few weeks regardless of how many new batteries I put in it. Way too expensive to not work appropriately.

I was lucky to test drive this mouse from someone at work. I quickly adapted to the new shape and the different way it worked. Wth the old style mouse, my hand would cramp up after several hours of working on the computer. I liked this Rockstick so much that I might get one for my personal home computer.

Bought it to see if somebody had done anything better than the Evoluent Vertical Mouse. It is about 6 years old and due for replacing.The "no finger clicking" might work for some people. But if you anything that require precise double click to terminate a line draw, don't try this.Also, I felt immediate muscle tension in my forearm using this. Never felt that with my Evoluent.There are not a lot of choices out there for lefties for ergo mouse products. This one was unable to best the EVM.

This mouse eliminated the pain in my hand from using a regular mouse. Unfortunately, it died within a year. For $80 it is not worth it. So disappointing!

This mouse really is a good alternative to the standard flat palm mouse. Comfortable, easy to switch hands, and scrolls with ease. My only complaint is that it's not a very good gaming mouse, and using it as one can cause some wrist fatigue.

I wish someone else with better manufacturing processes would make these. It alleviates all the wrist pain me and my partner had when clicking with normal mice and ergonomic trackballs, but I bought three and all three quit working. It's junk.

This has changed my life with carpal tunnel. THANK YOU. So easy to use. I bought 3. One for work, one for home and one for travel.
