Cooler Master MM731 review: a decent wireless FPS gaming mouse

The Cooler Master MM731 is a gaming mouse that goals to minimise interruption underneath hand. It’s light-weight, wireless, and there is nothing too complicated about its development or design. With a price ticket safely tucked underneath the $100 mark, it is not prohibitively priced, both. Though, that stated, I am unable to be too zealous in my reward, as there are a couple of flaws that preserve this mouse from contending with the most effective in a crowded market.

What is basically a no-nonsense gaming mouse, the MM731 favours FPS avid gamers in its simplicity. There are two main switches on high, a scroll wheel, an RGB-backlit Cooler Master emblem, and two thumb switches on the left-hand aspect. Flip it over and you will find a Bluetooth/USB/2.4GHz swap, LED standing mild, a pairing button, and a DPI swap. There’s additionally a little slot so that you can retailer the USB wireless dongle when not in use, which is a good contact.

The MM741’s fundamental promote is the wireless connectivity on supply: 2.4GHz by way of the supplied USB dongle or Bluetooth direct to your gadget.

Cooler Master’s wireless know-how works effectively on each counts. The 2.4GHz is supplied by a small USB Type-A dongle, and immediately connects your PC to your mouse as soon as powered on. There was no perceivable latency with this connection, both, even when plugging within the dongle on the cluttered rear I/O of my PC.

As for Bluetooth, this is not the connection I might advocate for gaming, because the extra extensively used Bluetooth connection is not fairly as succesful as its devoted 2.4GHz counterpart. The polling price alone is severely decreased on Bluetooth. That stated, there’s extra flexibility in providing it, and it will probably come in useful if you’re missing ports or enjoying on a gadget with none obtainable. For instance, I used to be ready to make use of this mouse on my Dell laptop computer, which solely gives USB Type-C connectivity, and with out utilizing up the one treasured port my USB Type-C to Type-A adapter gives.

I discovered myself utilizing this mouse on-the-go greater than my typical Logitech G Pro Wireless Superlight as a result of it lacks this Bluetooth performance. So that is a win for Cooler Master.

The mouse can be operated whereas linked by way of the included cable. This is a light-weight and versatile USB Type-C to Type-A cable, because the mouse itself comes with a Type-C connector, and will not intrude together with your gaming whereas the mouse is charging. A cable that tugs and redirects your mouse whereas in use is a little bit of a pet peeve of mine, so good to see Cooler Master get it proper.

On the matter of weight, the Cooler Master can also be supremely light-weight. By my reckoning, It weighs in at 58g, with out the cable or USB dongle. That’s lighter than the Logitech G Pro Wireless I’ve been utilizing as a benchmark, by round six grams.

Though, it should be stated, the Cooler Master feels the cheaper of the 2 for its weight-saving. The general end could keep away from the precise pitfalls of a honeycomb shell, but it feels tough to the contact. It feels cheaper than most comparably priced mice I’ve used, and if you’re spending fairly a lot you need it to brandish a sure high-end high quality.

There has been some effort to mould the general design higher to a gamer’s grip, although, and the mild slope up and away from the left-hand aspect of the mouse does make for a comfy grip. Unfortunately, nonetheless, the 2 thumb buttons should not precisely the place I’d like them to be, that means I sometimes discover myself within the thick of battle in Hunt: Showdown having to roll my thumb upwards to melee, which I’ve programmed to the rear of the 2 thumb switches.

Granted, completely different grips will beget completely different outcomes right here, and a few could discover the positioning is extra beneficial than others.

The Pixart sensor tracks my actions in-game and in our testing software program effectively, however I anticipate nothing much less from a PixArt sensor. The sensor really sits relatively far ahead on the gaming mouse, which in all probability will not make a lot distinction to most. However, that’s fascinating to gamers that want to aligned the sensor with the tip of their thumb or fingertips for max accuracy, and the MM731’s positioning is notably additional ahead than the Logitech G Pro Superlight.

In programming the MM731, nonetheless, I bumped into my largest concern with this mouse: the software program.

Cooler Master’s Masterplus software program lets it down. The MM731’s software program could also be among the least polished I’ve used. It’s clunky, and the person interface appears to be like half-baked at greatest. My fundamental bugbear is with the LED that illuminates to completely different colors on the underside of the mouse if you swap DPI, which isn’t represented in any respect throughout the app. That means you need to set your DPI settings within the app, save them, after which cycle by way of the mouse to determine which color represents which DPI setting by way of trial and error.

The general performance within the Masterplus software program is usually there, however it simply does not really feel in any method intuitive to make use of, and it finally ends up feeling like one other small element that takes the shine off this in any other case decent wireless gaming mouse.

There’s nothing majorly unsuitable with the Cooler Master MM731, however it additionally struggles to nail down something notably effectively both. It feels very very like a $60 mouse, at greatest, and even then it is dealing with stiff competitors, most of all from Razer. But in actuality it is sticker worth is nearer to $90. When the wireless gaming mouse market is so fiercely aggressive, the MM731 does not do sufficient to win me over or draw my money away from the pull of the most effective wireless gaming mouse on the market.
