I tested the RatpadzGS using multiple First Person Shooter games, and I found that my aim and accuracy did noticeably improve when compared to a traditional office-grade mousing surface. The intricate feel of the Ultraslick™ surface feels nice, and the mouse easily glides across the pad. The dimensions of the pad are 11.5 x 9.3 inches, so there is plenty of movement allowed without the worry of roaming off of the surface.
