Large, 3367 Optical, Omron Switches, 120g. This is one of the biggest gaming mice I've ever used and actually feels bigger than the DeathAdder, so for people with big hands, this might be the mouse you wanted... unless you don't like 120g+ weight. The mouse has almost everything else right with build quality, sensor, buttons and functionality... so it's a top mouse for what it is, but obviously won't suit everyone.
