RatpadzGS® is a Gaming Surface that has been designed by gamers, tested by gamers, and built by gamers. In fact, the new RatpadzGS took over a year to develop and is what we consider to be the best all round PC mouse surface for both roller ball and optical mice. During a major national gaming event, we handed out over 1,500 RatpadzGS prototype pads to all types of PC gamers, listened to their feedback, and made improvements. Then we tested the RatpadzGS surface with every major brand of mouse on the market to make sure it worked with all of them. It does.
