Title: Painful to use, and the scroller gets stuck.
Review: This is hands down the worst mouse I've ever used. I'm a programmer at a design agency, so we all use Macs, including this mouse. Repeatedly using this mouse over many hours cramps my hand, wrist, and shoulder on my right side. I recently worked overtime on a Flash website, and at the end of the deadline my hand was so cramped it was painful to extend my first finger.Aside from the less than optimal mouse shape, the biggest problem is the scroll dot. The more use your mouse gets, the more likely it is to stick so you can't scroll at all. You can unstick it by holding the mouse upside down and vigorously rolling the ball in all directions. However, despite doing that regularly, I still have problems scrolling up with it. It takes more force to scroll up now, which cramps your hand and stresses your wrist.I do not recommend this mouse for anybody who uses a computer more than a few hours a day.
