Query: Amazing lifetime device

Quicky and short: This is the best mouse I ever had (and I had a lot and still have others much more expensive)Just use a correct mousepad and keep it clean from dusty (which may produce undesired effects like shaking mouse pointer or erratic/involuntary movements) and that is it... oh, and a good pair of alkaline batteries too. ;)Im using mine since august 2005, every day (from 10am to 4am) and not a single problem at all.
