The mouse is accurate etc ... nothing to say. the point on which we had never been satisfied until now is the battery consumption. With this mouse is it is a miracle. It consumes little hyper. Apparently she goes to sleep and does not consume anything very quickly when you not use it and wakes up as soon as you click on it. Result: Since he has has not yet changed the batteries and I can say that I use every day of my computer. Very very satisfied. Bye bye logitech mouse and other "brand"
