      1. The answer to Carpal Tunnel Syndrome but... 4 Star Review

        Posted by on Feb 13th 2013

        First, I love the joystick mouse. It really has helped tremendously with numbness and pain in my wrist and hand. I have 2 of them in fact. the one I use with Windows, at work, has been a real treat. The only issue is the left click button sometimes is difficult to use because it over selects what you want. On the Mac, at home, though you lose the function of the third button. At work I very much appreciate the scrolling option of the third button. Also the one at home the left click button sticks sometimes which is really annoying. Otherwise I live by these things...

      2. Nice, but doesn't last long 5 Star Review

        Posted by on Apr 11th 2011

        I've been using the 3M Ergonomic mouse for several years. My original wired version still works after about 6 years of use. My one-and-a-half-year-old wireless version recently stopped working. At first, I'd have to click several dozen times at the beginning of each day for it to work reliably. Now, the cursor doesn't move at all. Changing the batteries doesn't help. At the time I bought it, I saw other people complained about the same problem, but I liked the idea of using a wireless mouse. I guess I'll go back to the wired version.
