Tiny Mouse For Tiny Mitts

Cooler Master MM710

Portrait of Tammy Strobel

I really hope holes don’t bother you, because here I am with yet another holey, ultralight mouse. The MM710 has many of the trappings of a great mouse for FPS players. It is super light, weighing a mere 53g, and has a small-ish, comfortable shape and a flawless optical sensor. And given that mouse manufacturers are now finally paying attention to their cables and trying to make them as soft and supple as possible, the MM710 also comes with its own flexible “Ultraweave” cable that has near zero drag.

The MM710 is a small mouse made out of plastic to keep weight down. It measures just 116.6 x 62.6 x 38.3mm and flares out toward the back for a slightly wider rump. As a result, it feels a little wider in hand than I’m used to, but it’s short enough so that’s not much of a problem. However, it’s almost a no-go for palm grippers with larger hands. My hands measure 16.5cm from the base of my palm to my fingertip, so I’m still able to palm the mouse. However, it definitely won’t be the best fit for everybody.

It’s great for wrist aiming though, and its short body and light weight makes it really easy to make small adjustments to your aim using just your wrist.

This is basically a MasterMouse S with holes and other improvements, such as a more centralised sensor, and I think Cooler Master has taken a mouse with a great shape and turned it into an entirely new beast. For one, the MasterMouse S had a terrible cable that was notoriously stiff, but the MM710 is on the other end of the spectrum entirely with a supremely flexible and supple cable. The sleeving also looks neater and tighter than on the Air58 Ninja and Model O, both of which have cables that seem to puff  out in random areas.

It’s also ditched any form of RGB lighting to bring the weight down. However, if you really must have some lights, Cooler Master is also releasing an RGB version of the mouse, the MM711 later in October. Of course, it’ll weigh slightly more, but that’s the price you pay for additional features.

Once again, I can’t stress enough how much of a difference the 53g weight makes. You probably can get away with a mouse that weighs closer to 100g in less demanding single-player titles, but when it comes to twitch reaction shooters that require rapid flicks and precise tracking, the lighter mouse is noticeably less fatiguing after long hours. Even something like the Zowie S2, which isn’t even that heavy at 82g, feels almost like a brick in comparison.�

It’s almost funny to see how the pendulum has swung. The MasterMouse S actually had a weight inside it that weighed around 13g. This was not a configurable weight and was just a metal piece screwed on to the top shell to convey the impression of heft, because people tend to associate weight with quality. In 2019, the idea of that is laughable, and I’m glad that Cooler Master has redeemed itself wonderfully with the MM710.

The sensor inside the mouse is a 16,000DPI PixArt PMW3389 optical sensor, which is a top-notch sensor with no known acceleration or prediction. Tracking was flawless, as expected, which is pretty much the norm on all top gaming mice today.

However, one area that could use improvement is the stock mouse feet. There’s some scratchiness out of the box, probably due to the fact that they don’t have rounded edges. Things improve quite a bit after breaking them in though, and they end up being quite usable.

Other than that, build quality isn’t much of an issue. There’s no flexing when pushing on the top or sides of the mouse; the scroll wheel has well-defined notches and is quiet. And while the buttons do have some slight wobble from side to side, it’s not something I noticed when gaming.�

You’re also probably worried about liquid or dust getting into the mouse. While it seems like it’d be easy enough to clean out the internals with an air blower, Cooler Master says that its PCB is also splash- and dustproof.

The Cooler Master MM710 is hands-down one of my favourite mice of 2019. It truly offers a winning combination, comprising a small, comfortable shape, extremely lightweight design, flexible cord, and a flawless sensor. The $99 price tag just seals the deal for me.

If you like smaller mice, it’s hard to do better than the MM710.

There are holes on the bottom of the mouse as well.
