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: genuine 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 super-lightweight, revolutionary new ergonomic shell design without holes that reduces the weight to <59g, the MM731 truly is less than the sum of its parts.
