Cooler Master MM712 review

Cooler Master's new wireless gaming mouse includes Bluetooth connectivity and is even lighter than its hole-filled, wired sibling the MM711.

Our Verdict


The Cooler Master MM712 is a very capable wireless gaming mouse for a good price, but its shape won’t suit some users.

Cooler Master’s recent gaming mice have largely impressed us, with the MM711 being our choice for the best lightweight gaming mouse in our best gaming mice list. The new Cooler Master MM712 is a variation on that very mouse, adding wireless connections and numerous other changes.

The biggest and most visually obvious change is that the MM712 no longer sports external weight-saving perforations. Instead, the company has sealed the mouse back up and kept its weight-saving endeavors to internal tweaks.

Overall, it’s a move that makes a lot of sense, as while exterior holes offer an easy way to reduce weight, they expose the innards to grot and grime from the outside world. What’s more, the MM712 is 2g lighter than the MM711 so it’s clear the exterior holes aren’t needed to create a very light mouse.

Thanks to that external change, the MM712 cuts a clean, minimalist figure, especially in the black finish of our review sample – a white version is also available. The RGB-illuminated Cooler Master hexagonal logo on the rear provides just a little bit of flair without breaking the otherwise clean look of the mouse. The symmetrical shape also helps create that clean look, though like many symmetrical mice it lacks side buttons on the right edge to make it a truly ambidextrous design.

The MM712 is small, with a length that’s around 10mm shorter than the likes of the NZXT Lift or Logitech G Pro X Superlight. Despite this stubbiness, the back of this mouse flares out to be as wide as larger mice, giving it sides that angle inwards towards the front. We found this made it less of a universally appealing shape and best suited to a fingertip grip, using just your little finger on the side.

In addition to having a 2.4GHz wireless connection, the MM712 houses a USB Type-C port on its front that can charge and connect the mouse to your PC. Plus, it supports Bluetooth, which comes with the bonus of more than doubling the battery life over using the 2.4GHz wireless dongle, though it doesn’t have the bandwidth for very fast-paced gaming.

A hole on the underside of the mouse can store the wireless dongle. However, It’s covered by a rather flimsy plastic flap that we can see easily snapping off and getting lost.

Also on the underside of the mouse is a DPI button, a slider switch for changing between Bluetooth and wireless modes, plus there’s a pairing button. Up top, you get just four buttons and a scroll wheel/middle button, all of which feel precise and entirely well-suited to the high demands of intense gaming sessions.

The MM712 uses an unspecified PixArt optical sensor with a maximum DPI of 19,000, maximum acceleration of 50G, and maximum movement speed of 400 IPS. It’s a top-notch sensor that performed flawlessly in our tests.

Meanwhile, the lighting, polling rate, DPI, lift-off distance, button assignment, wireless sleep mode, button response time, and more (it’s a comprehensive list of settings) can be controlled via Cooler Master’s MasterPlus software. However, the software insists on filling your entire screen (at 2,560 x 1,440) even when in windowed mode, which is annoying.

Cooler Master MM712 review conclusion

The versatility of wired, wireless, and Bluetooth modes makes this a great all-rounder mouse, while its gaming performance is flawless. Only its shape may be of concern to some as its short length and flared rear doesn’t have universal appeal, being best suited to smaller hands and fingertip grip.
