Cooler Master MM731 Wireless Lightweight Gaming Mouse Review | Lightweight FPS Perfection



Along with choosing which class to throw, choosing a mouse is one of the most important decisions a player can make. As the primary means of control in our fantasy worlds, it is imperative that you find one that fits your purpose. If you are looking for something to elevate your FPS gaming experience then Cooler Master might have the answer for you. Part of their new line of gaming mice is the MM731 Wireless Lightweight Gaming Mouse. Weighing in at just 60g, this is one of the lightest mice I have ever used. As such, it is also quickly becoming one of my favorites.

Let’s take a tour

If you showed the MM731 to someone, they wouldn’t think it was anything special until they picked it up. That’s what I like about it. The design is incredibly understated, taking the form of a generic mouse with a matte black coating. A faint Cooler Master logo can be illuminated in RGB lighting if desired. However, leaving the light off makes the mouse look sleek and professional.

Upstairs, nothing fancy. There are your usual left and right click buttons flanking a scroll wheel. These are equipped with optical switches which are apparently more responsive and durable over time. While I cannot say that they are durable over a long period of time, they are most definitely responsive. I didn’t miss a single click in my testing, and the switches didn’t get stuck or faulty.

The scroll wheel is rubberized for excellent grip, and it moves in distinct stages. However, while the distinctive scrolling steps are great for switching weapons in games, it can be tiring when scrolling through web pages. If gaming is your primary use, that won’t be a problem. But if you are planning to use this mouse for productivity as well, this is something to keep in mind.

On the left side of the mouse are two programmable buttons. These can be returned to any command you like in the MasterPlus software, making them versatile if you want to set up custom macros. They have a very satisfying click, which is more than what can be said for even some of the more high-end mice. Unfortunately, these buttons cannot be swapped on the right side of the mouse. For left-handed people, I’ll have to look elsewhere, I’m afraid.

Fit and feel

The matte black plastic does a fantastic job of giving this mouse a premium feel. Even with its light weight, there is absolutely no flex or crackle on the body when it is tightened firmly. I wouldn’t trust it to be thrown around the room, but it is most definitely durable. The matte finish also repels fingerprints really well, so greasy snack stains won’t show up as easily.

Overall, the MM731 does nothing to break the mold in the design of its form. If you’ve used something like the Logitech G Pro Wireless or the Razer Deathadder, you’ll probably feel right at home with this mouse.

That said, it’s still slightly smaller than I would like. As a person with relatively large hands, I tend to prefer using a palm grip while wielding a mouse. However, the MM731 tends to promote a claw or hybrid style grip for those with longer fingers. The smaller size probably plays a role in how light the mouse is, so that’s a bit of a tradeoff. This is by no means a break-up, but something to keep in mind, of course.


The MM731’s biggest selling point is that it’s so light. Cooler Master has managed to reduce this mouse to the essentials, while still filling it with RGB lighting. The result is a mouse that glides effortlessly across the mouse pad. The lack of cable also helps in this regard. With nothing to hook, you can move the mouse completely freely without ever encountering an obstacle.

The result is that I have never felt more in control of my mouse movements than with the MM731. When configured with the same DPI settings as my previous mouse, I already felt myself getting even more precise than before in FPS games like Valorant. Even while browsing my desktop for business purposes, I felt I could open files and close windows with more precision than before.

What’s also great are the various connectivity options. A 2.4 GHz USB adapter is stored inside the mouse itself and is the most reliable option when you are sitting on a desk. However, the mouse can also be connected to other devices via native Bluetooth support. Because when you’re traveling on the go, all you have to do is carry the mouse with you and you’re good to go.

You can also connect to a PC using the included USB C cable. Even if you run out of battery, you will still be able to use the device. Not that you will often find yourself running out of juice. The MM731 is designed to last up to 72 hours of continuous use on 2.4 GHz and 190 hours using Bluetooth. After using the mouse for a 9-5 work week and several evenings of gaming, I haven’t needed to charge the thing yet.

Perfectly matched

I was also able to pair the MM731 mouse with the Cooler Master’s XL MP511 mouse pad. This no-frills accessory is the perfect match for the new wireless freedom of the mouse. The XL variant I have is able to cover my entire full-size keyboard while still leaving enough room for the mouse to move around.

There’s no fancy RGB to be found here, just a little Cooler Master badge in one of the corners. It stays in line with the understated look of the MM731, which I love. Anti-fray seams around the edge make this a durable cushion that also has a stain resistant coating. Sad to say I had to put this stain resistance to the test because I accidentally spilled pasta on it last week. Fortunately, it wiped off easily and left minimal marks on the fabric.

The only complaint I have with the cushion is that, even after a week of heavy use, the edges are still a bit unfolded. I tried to pin the corners of the rug overnight with heavy objects, but it refrains from lying completely flat. It doesn’t negatively affect my goal, but I wish the mat had settled in faster.

Software needs to work

While the physical build of the mouse is great, it’s in the software department that the cracks start to appear. Mouse adjustment is done through MasterPro software. Unfortunately, very little suggests that this is “professional” software.

For one thing, the software window refuses to let you resize it, which means it takes up the entire screen when opened. It’s also incredibly buggy. When I try to move the window to my second monitor, it ends up flipping the whole window, making the software useless.

Despite its heaviness, the software is mostly functional. Fortunately, you can change the settings, then close the software and forget about them. There are options to link all mouse buttons together, adjust DPI and takeoff distance, and play with RGB lighting. These are all the settings you could possibly need for a mouse, offering a lot of customization.

Competitive price

Taking stock of the performance of the MM731 is impressive considering its price. Priced at £ 89.99 in the UK, this cuts down on many esports-focused wireless mice on the market that offer similar functionality. I previously used a Logitech G Pro Wireless which costs £ 139.99, and honestly? I think I prefer the MM731.

It’s not perfect – the software is lackluster, it’s a bit small for my taste, and MMO gamers and productivity freaks might prefer to have more programmable buttons. However, the cordless convenience, ultra-light construction, and exceptional build quality are enough to earn it a permanent place on my desk.
