With over 10 million units sold, the SteelSeries "QcK" is the epitome of surface performance and innovation. The microfiber surface, exclusively manufactured for SteelSeries, allows for precise control for all play styles. The enhanced surface coating has been tested by the leading mouse sensor manufacturer, which developed the SteelSeries TrueMove sensors based on this: optimized accuracy of mouse tracking for both optical and laser sensors. Stitched edges ensure that the material never frays or peels off. The fabric surface "QcK Edge" is ultra-durable and washable: a clean surface can make the difference between victory and defeat. The durable and non-slip rubber base is designed to eliminate unintended movements and provide a solid platform for competitive gaming. For the past 15 years, the SteelSeries "QcK" has been the mousepad of choice for eSports stars. eSports athletes have won more prize money with SteelSeries products than with any other brand.
