You have so many different mousepads, what's so special about the SteelSeries HD series?
SteelSeries 9HD, 4HD, and 3HD are hard plastic mousepads 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.
The HD series is our premier surface for laser gaming mice, though it provides excellent tracking with optical mice as well.
