Cooler Master MM720 review: Compact gaming mouse with powerful sensor

The compact Cooler Master MM720 gaming mouse follows in the footsteps of the once popular Spawn and Xornet models, but is smaller and, above all, considerably lighter in direct comparison. Our test reveals what the 50-gram rodent with its unusual design has to offer.

Design and Features

Cooler Master packages the MM720 gaming mouse in an eye-catching purple cardboard box complete with black details. In total, the manufacturer offers four color options: offered are one matte variant each in black and white, as well as two glossy counterparts in the same colors.

The small dimensions of the packaging already indicate that we are dealing with an extremely compact representative. When opening the box, this first impression is quickly confirmed. Besides the MM720, only a 3-page quick-start guide and an additional pair of gliding feet are included. There wouldn’t be room for more in a package that’s barely bigger than a box of tissues.

When looking at the gaming mouse, the unusual design of the MM720 is immediately noticeable. The gaming mouse turns out very short with a length of 107 mm, but is unusually wide with a maximum width of 77 mm.

In terms of ergonomics, it quickly becomes clear that the gaming mouse is only suitable for right-handed users. However, these are excellently served when using the fingertip or claw grip: The MM720 lies excellently in the hand and impresses with an unagitated yet appealing design including a honeycomb pattern on the mouse’s back and sides.

In combination with the low weight of only 49 grams, this makes gaming a joy. The gliding properties of the PTFE feet are also pleasing and are especially convincing on a fabric mouse pad. Those who primarily play with a low mouse sensitivity will hardly feel the gaming mouse even during longer sessions due to its weight and convincing shape.

Cooler Master relies on durable LK Optical Micro Switches for the two primary mouse buttons, which are supposed to withstand a whopping 70 million clicks. They also convince with a pleasant and precise pressure point. The same can be said about the scroll wheel, whose pressure point is also convincing, but is a bit too smooth and lacks the necessary precision. Due to the low grid, it is not uncommon for the mouse wheel to spin a bit during clicks.

There are also two more switches on the left side, which brings the total to six buttons together with the DPI switch on the underside of the mouse. The position of the left buttons is okay and the pressure point is also good, but these buttons are also not free of flaws and do not look quite as high-quality as we would have liked due to the smooth surface.

In terms of workmanship, however, the Cooler Master MM720 doesn’t make any mistakes. Even when exerting a lot of force, it is almost impossible to dent the case – even in the honeycomb area. Despite the holey design, Cooler Master achieves an IP58 certification, which theoretically even protects the rodent against running water.

Of course, a gaming mouse should not be without an appealing RGB lighting. In this case, the illumination penetrates the entire honeycomb pattern, while the mouse wheel can also be set in scene. The color scheme can also be adjusted by pressing the mouse wheel and one of the two side buttons (or with the help of the software). The 1.8 meter long, fabric-covered cable also turns out positively. It is very flexible and not annoying at any time, even in intensive gaming use.

Sensor and field test

Cooler Master relies on the precise PixArt PMW-3389 sensor for the MM720 gaming mouse, achieving a maximum optical resolution of 16,000 DPI. This can be adjusted to a total of seven levels (400, 800, 1,200, 1,600, 3,200, 6,400 and 16,000 DPI) using the button on the bottom, while a brief colorization of the RGB lighting informs you of the current selection.

The very low lift-off distance of less than 2 mm should also be mentioned positively, which – as already mentioned – is especially suited for low-sense gamers. With a polling rate of 1000 Hz and a speed of 400 IPS, the gaming mouse is almost completely convincing when gaming.

However, it is worth mentioning that the sensor is not located directly underneath the scroll wheel due to the mouse’s design, but has moved minimally to the back. This hardly makes a difference in most cases, but it is quite noticeable especially at high DPI values beyond the 3200 mark. Here, we noticed the mouse pointer occasionally moving to the upper right in the test. But that’s complaining on a high level, overall the MM720 is almost completely convincing.

Especially in combination with some fine-tuning in the accompanying MasterPlus software, the handling in gaming and office mode is pleasing. Even fast shooters like Apex Legends or Splitgate are mastered by the MM720 without fault.

Due to the unusual shape, however, we cannot give it an unqualified purchase recommendation. Especially for large hands, the shape is not fully convincing, which is why you should definitely try out the gaming mouse yourself before buying it.


Optional, but quite useful, is also the use of the approximately 700 MB Cooler Master MasterPlus software. This not only enables the obligatory adjustment of the RGB lighting in two zones, but also offers extensive setting options.

For example, the software can be used to freely configure the assignment of the six buttons. The adjustment of the mouse performance is also particularly extensive: The seven stored DPI levels can be individually adjusted here for the X and Y axes. In addition, it is possible to change the polling rate and even the double-click speed and key reaction time.

In addition, the software can be used to create and save various individual profiles. It is also convenient to create macros with it. All in all, the software provides many clever setting options, some of which even go into much more detail than you are used to with the competition – however, due to the lack of explanations, some of the options might simply overwhelm newcomers.


With the MM720, Cooler Master delivers a convincing gaming mouse that is particularly pleasing in terms of build quality. We also liked the compact size and the low weight in the test. Similarly, the high-quality and precise primary mouse buttons confirm every click with a clear feedback, as well as the strong PixArt PMW-3389 sensor.

However, due to the unusual design and size, the MM720 cannot be given a clear buy recommendation. Especially users with large hands, who are also usually used to the Palm grip, should definitely hold the gaming mouse in their hands before buying it.

However, those who have rather small hands and usually rely on the claw or fingertip grip will really enjoy the mouse after a short period of getting used to it. The only reason for criticism is the slightly too smooth scroll wheel. If that doesn’t bother you, or if you’re a fan of the Spawn and Xornet models anyway, you’ll get your money’s worth with the Cooler Mater MM720.
