omg everyone says G5 mouse is the greatest, mine broke, still lights up, and u can change the dpi from the mouse btu no movement at all from screen(you can right click and a box comes up, i know its plugged in right) i should rma but im lazy
it might have been something i did like sit on it but i doubt that would even cause it its a real strudy mouse, i would still say its an awsoem mouse but anyone thats spends $50 on justa mouse is pretty dumb, it just moves.....
