Designed specifically for 3Dconnexion CadMouse, the pad allows effortless, precise mouse movements thanks to perfectly balanced static and sliding friction. So you always have your mouse movements under control. The smooth, even surface of the 3Dconnexion CadMouse pad with its reflective properties ensures precise sensor measurement and smooth, precise cursor movements. For this reason, the robust three-layer 3Dconnexion CadMouse Pad has a solid top layer and a silicone underside. These ensure a stable and even surface.
