The MM831 has all the features you need and love in a gaming mouse, plus truly cord-free, lag-free connectivity. It features all the hallmarks of a legit mouse: pro-grade internals, thoughtfully ergonomic design, RGB lighting, and durable construction. But the addition of hybrid wireless connectivity plus Qi-compatible charging equals truly wireless fragging functionality. The MM831 doesn't just stand on its own -- it stands out from the rest of the pack. The MM831 is outfitted with an optical sensor that can track as high as 16,000 DPI. That means no lag, no stutter, and no fighting with your mouse in the thick of it. And in case you need to favor pinpoint precision over speed, the DPI is instantly adjustable, giving you the ability to make real-time adjustments based on playstyle, class, and type of game. The MM831 is built for cordcutters and stubborn traditionalists alike. Operate the mouse in legacy wired mode, or ditch the cord for two types of wireless functionality: lag-free 2.4GHz wireless or state-of-the-art Bluetooth connectivity. There's no need for that charging cable anymore: wireless charging enables the MM831 to refuel its juice simply by placing it on a Qi-compatible charging pad device. Welcome to the world of tomorrow!
