When I say that I mean no pain, no fatigue, no carpal tunnel. Buy this product for yourself and find out for yourself. I found out about this because we hired a girl in the office that was an artist. It was all she used. Turns out this is the mouse a lot of artists like because of the precision and lack of hand fatigue. Only takes a couple of hours to get used to.
