I bought this mouse because she looked very stylish but looked at from near total so badly processed caves one can talk of luck that keeps them together at all but it works and that's why I keep them. For the price you would have to expect a little better processing, therefore only 3 stars. It works really well, it seemed to me that as if the PC must get used to the mouse because it has only tightened in total movements but after a time it is no longer like that. I guess you can buy but it is not primarily a buy recommendation prefer 5-10 euros more to spend then it is processed properly. It works very well when playing with the modifier keys For example, Left 4 Dead 2, I left the keys to set the it acts for flashlight on and off and zoom weapons. Who can not pays so much detail on `buy calmly.
