The surface of the MM400 is made from a high-quality, long-lifespan polymer. It's tuned to deliver outstanding glide characteristics without sacrificing control, allowing for both consistent snap targeting & pixel-precise shots. The tuned micro-texture surface is optimized for gaming sensors, so you get a better glide feel without sacrificing control or accuracy. The CGMM400 is stable & secure. You can't afford to have your mouse surface move in the middle of a firefight, so Corsair added a non-slip base that provides cushion with just the right amount of give. & it's made from natural rubber, so it doesn't have a harsh chemical odor.
