Title: 3M Ergonomic mouse
Review: I bought the 3M ergonomic mouse because of excessive pain and swelling in my right index (mouse) finger for several weeks. Since using the mouse for about 3 weeks the pain is gone. The thumb mouse button is easy to use, but aiming and moving the mouse around on the page is harder to master. It can be done though with patience - but the first week is rough. So, if you can put up with the learning curve, you'll be glad you did.
