Rated 5 out of 5 by from Ease of UseI have used this mouse for both design work and casual use. It has lasted me about 5 years before it finally died and I`m going to buy another one. The use of this mouse has saved my wrist from cartilage damage. I only have a few things I did not like about this mouse and that is listed in cons section below.
