Cooler Master MM710 Review

By Edward Chester. Posted

The Cooler Master MM710 is the latest addition to the new wave of ultralight gaming mice. Weighing in at just 53g, it is indeed one of the lightest mice available, and with an asking price of just £40 inc VAT, it’s one of the cheapest ultralight models too.

The MM710 keeps down its weight by having much of the outer casing perforated. The entire back two-thirds of the mouse are punctured by hexagonal holes that help shed tens of grams (the similarly-shaped CM110 weighs 92g).

The downside to all those holes is that they open the internals up to invasion by dust and spilled drinks, although Cooler Master has thought of this and given the interior a dust-and-water-resistant coating. You’ll want to avoid dunking it in your tea, but it should help the MM710 survive the odd splash.

Some users may not be keen on the feel of the holes, but we’ve really come to appreciate the extra grip provided by the holes on the Finalmouse Ultralight 2, and wish the likes of the MM710 extended the holes along the full length of the sides too. The plain plastic surface, where your fingers grip the mouse, can get a little slippery when you have cold, dry hands.

The overall shape of the MM710 is intriguing too. It’s quite small, but it has a back-heavy design, with the main hump of the mouse towards the rear. Likewise, the natural gripping point on the sides, is around a third of the way back rather than in the middle. As such, it’s not particularly comfortable to use in a fingertip-grip style.

Instead, it’s best suited for palm grip use by gamers with small hands. The back is also too slippery to provide a good purchase for a claw grip. As ever, this all depends on the size of your hands and how you play, so we always recommend seeing if there’s a way to try a mouse before you buy it.

As usual with a lightweight mouse, there are few features. You get Left, Right, Middle and a top DPI button, plus two thumb buttons on the left. There are no thumb buttons on the right, so this isn’t a truly ambidextrous mouse despite the shape. Meanwhile, the braided ultralight cable has a looser style of braiding than normal, and the cable underneath is very soft and flexible. This greatly reduces the resistance of the cable so it doesn’t disturb your aim. It feels great.

The MM710 also uses the excellent PixArt PMW3389 optical sensor, and has 20 million keypress-rated Omron switches for its left and right buttons. The sensor’s DPI can be switched between up to seven different levels by the top button, with the levels set via Cooler Master’s software. You can also adjust button response time, double-click speed, angle tunability, lift off distance and polling rate. As we’d expect, the MM710 performed flawlessly in terms of tracking and button response – most mouse sensors and buttons are just so good these days.


The Cooler Master MM710 is a good-value, highly-capable addition to the ultralight gaming mouse roster. It has a very simple design, but it performs well and has an intuitive button layout. It’s also easy to program via its software. However, the shape could be improved – it’s best-suited for gamers with small hands who use a palm grip – gamers who have larger hands will find it a bit uncomfortable to use.

Another good addition to the ultralight mouse market, but only for small-handed folk.
