The basic functions of this mouth operate just as well as you would expect: the buttons function smoothly, the wheel works well, and the entire thing is plug & play on my laptop running Windows XP Home.This mouse is NOT, however, suited for gamers.Simply put, the optical tracking system is far too unresponsive. What I mean is this: attempting to move the mouse quick from one side of the screen to the other will result in the optical sensor failing and the cursor simply getting confused instead of making the trip across the screen. Gamers (especially the FPS variety) will find this an extreme detriment to their gaming ability. Invest the extra money and purchase a Logitech mouse with MX Tracking technology - they're much more accurate and responsive, unlike this cheap, clunky device.
