This mouse is pretty good for my small hands, so i get a lot less wrist pain than i've had with previous gaming mice in the past that were often bulky with a lot of extra buttons. The thumb buttons on this mouse are very handy, and provide just the right number of extra buttons that i need for most of my favorite games. My only complaint is that the 2nd thumb button is a little sticky. I often have to "warm it up" with a few presses before i start my game, or else it doesn't depress and activate as easily as i would like. The sensor seems great and responsive and has no trouble on my large, cloth mouse pad. The weight seems good, though i wish that it was perhaps a little heavier. That's just personal preference, though.
