At just 45 g, the MM730 is as light as two AA batteries while the MM731 isn't that far behind at 60 g. These ultra-light mice even come with the usual RGB LED and other customizable features commonly found on heavier gaming mice.

If you're in the market for one of the lightest gaming mice you can find, then the latest Cooler Master wired MM730 or wireless MM731 may be worth a closer look. These mice come in at around 45 g or 60 g each without needing to sacrifice key features gamers have come to expect such as PTFE feet, RGB lighting, multiple modes, button remapping, and on-the-fly DPI switching.

The manufacturer sent us a wired MM730 for our review and, unsurprisingly, the weight of the mouse was the first thing we noticed. Its firm but thin plastic chassis is so thin that the internal LED lighting can even shine through the material on the bottom. The very low weight makes it easier on the wrist during longer gameplay sessions.

All buttons on the mouse are clicky and responsive as one would expect, but the two thumb buttons on the side are a bit softer than the two main buttons and so feedback is not uniform between all buttons. Additionally, the center wheel is rigid with no free-scroll toggle option.

The MM730/731 relies on the MasterPlus software for nearly all of its auxiliary features much like with other Cooler Master accessories. The software itself is annoyingly large at over 300 MB, but skipping it would mean losing the ability to customize lift off distance, angle snapping, polling rate, button response times, button mapping, and RGB options. By default, pressing down on the center wheel will toggle between two different profiles which can be handy when switching between two different games or applications. All seven inputs, including the DPI button on the bottom and the wheel scroll, are customizable by the user.

There are a couple of potential drawbacks worth mentioning. For one, the textured matte surface for the palm and fingers will likely become glossy from oil buildup over time much like on many plastic keyboard keys. Users may want to choose the white version of the mouse which may better obscure any fingerprint buildup. Secondly, we would have preferred more PTFE along the left and right sides of the bottom surface instead of just the top and bottom for better coverage. It looks as if the manufacturer went the cheaper route by having just a small PTFE circle over the sensor. Of course, users can always stick on more PTFE themselves.

The Cooler Master wired MM730 and wireless MM731 are now shipping for $79 and $89 USD, respectively, each with two-year manufacturer warranty as standard. More technical details on the mice can be found on their official product page here.
