The MM531 by CoolerMaster uses an Optical sensor from Pixart, specifically the PMW-3360, providing a DPI/CPI range of 4 Levels (100~12,000dpi). This is combined with a 32 bit ARM Cortex M0. This results in a tracking speed of 250 ips, and a maximum acceleration of 50g. It uses a USB, Gold-plated connection with a 1.8m cable. It weighs in at 131 g grams with the cable and 92 g without the cable and is approximately 60.4 x 40.2 x 124.8 mm (LxWxH).
The MM531 is the worthy successor to the CM Storm Mizar - this time upgraded for the serious gamer. It features sleek ergonomic styling with moulding and side grips ideal for palm grippers. It also has the hardware features to match, with a precise Pixart 3360 lag-free 1:1 input, on-the-fly DPI adjustments up to 12000, and Omron switches for rugged durability. Well-balanced and packed with features, this a gaming mouse custom-tailored for high-action competition in first-person shooters.
