Have one with a ball (for the PC) which must be cleaned constantly. Constantly times when something had to be done precisely, trouble-free operation was not given and a cleaning again needed. My husband gave me time to try its cordless, everything was wonderful two hours then the battery was empty and the thing had to be charged or they had to be changed. The bugged as well as the cleaning of the other mouse.
I'm totally satisfied with this mouse, small, handy, responded immediately, despite cable what me but not stört.KLEINE mouse for little money !!!! Since I erlediege of all things from the netbook.
