Cooler Master MM720 Review

The Cooler Master MM720 comes up when people search for the lightest possible claw-friendly mouse, since its full honeycomb shell brings it down to just 49g.

That's lighter than most wireless mice while staying wired, and it pairs a flagship PMW3389 sensor with Kailh's GM 4.0 switches, making it one of the best value-for-weight picks in Cooler Master's whole lineup.

Extreme Honeycomb Weight Savings

Nearly the entire shell is perforated, shaving weight down to 49g, among the lightest wired gaming mice ever released, aimed squarely at fast-flick FPS play.

Flagship Sensor for the Price

The PMW3389 sensor tracks up to 16,000 DPI with excellent accuracy, matching sensors found in mice costing significantly more.

Comparison to Alternatives

Against the Glorious Model O Wireless, the MM720 is 20g lighter but stays wired only. Compared to its sibling the Cooler Master MM711, the MM720 uses a claw-shape symmetrical shell versus the MM711's more ergonomic lean. G-Wolves' HSK Pro undercuts it further on weight but at a much higher boutique price.
