I bought this mouse 8200DPI for my laptop because the surface of the table is plastic, it works very well the speed adjustment is easy on the mouse not require installed software running on windows I July 64 bits as the volume can be controlled even if it's not super accurate this helps anyway the button responds well the color of the mouse is not bad to be a little bit too much for me Flashi blue lol can also Alege mouse weight by removing those ki is convenient but the real under this mouse is really its size in the hand I think it's too big for me especially when I made the document has changed it's too heavy and moved not accurate enough for me So I preferred returned and refunded me otherwise it comfortable to handle and fast and neat deliveries thank you Amazon
