The mouse looks good, feels good in the hand, very good to use. However, it smells very unpleasant to rubber or plastic, or ... At the beginning of my hand smelled after so I washed my hands after each use. I've cleaned off with a damp cloth (the smell always very pleasant), but nothing helped. Over time, the smell can be by; my hand no longer smells of use. Perhaps each mouse smells once so terrible? I do not know, therefore I can not recommend it in good conscience. Maybe you go times into a store and smelling the exhibits)
