The MM731 retains the innovative, lightweight spirit of the MM710 Series while maintaining the familiar aesthetic of classic gaming mice. Each pro-grade feature is intended to give you lightspeed responsiveness in the blink of an eye: upgraded PTFE feet for unrivaled glide, hybrid 2.4GHz/Bluetooth wireless for supreme versatility, adjustable 19,000 DPI optical sensor, and optical micro switches for superior durability and input. With all of that housed in a superlightweight, revolutionary new ergonomic shell that reduces the weight to 59g without having to resort to a shell with holes, the MM731 truly is less than the sum of its parts.
