SteelSeries 4HD is a hard plastic composition specifically engineered for professional gamers who demand extremely consistent precision, accuracy and stability. The finely textured surface consists of tens of thousands of light reflecting microscopic points, optimized to enhance the tracking capabilities of next-generation gaming mice. Thanks to the sophisticated tracking capabilities of the surface, the user is capable of performing exceptionally precise mouse operations, both in terms of minimal movements as well as high velocity slingshots. This gaming surface was researched and developed in parallel with the SteelSeries Xai Laser Mouse to ensure that advanced high definition mice fully benefit from this surface. 11.4"W x 9.4"L x 0.08"H
