Cooler Master MM830 Overview
Cooler Master has designed the MM830 to be a pro-grade gaming mouse, with an ergonomic design. And while it does have some curves and shaping that lend it to being an ergonomic design, they are far from extreme, which results in a comfortable grip for most users. There is nothing too extreme shape-wise with the MM830, save for a bit of a thumb rest that extends from the left side of the mouse. While not huge, the MM830 does come in on the larger side of the spectrum, with dimensions of 82.2mm (W) x 130mm (L) x 43.4mm (H), and definitely filled up my hand when in use.
The body of the MM830 is PBT plastic, which is often referred to in the keycap world. Known for its resistance to wear and tear, this material gives the MM830 a solid feel. The surfaces of the mouse have a slightly textured feel, with just the right amount of grip.
Looking down from the top, we can see that the MM830 features an asymmetrical design, with the thumb rest on the left side being the most noticeable difference at first glance. Looking a bit closer, we can see that the left and right mouse buttons are slightly different in size, with the right button being slightly longer than the left. These buttons are also separate pieces from the rest of the upper mouse body, which is something a bit different from what we have been seeing in other mice. We have gotten used to the upper portion of most mice being a single piece, with the left and right mouse buttons being part of the upper mouse body itself.
Between the left and right mouse buttons is a mouse wheel with a slightly ridged texture for precise scrolling control. The mouse wheel is illuminated on both sides via RGB LED lighting through the transparent plastic that makes up the body of the scroll wheel. Just behind the wheel are three transparent plastic pieces that not only offer RGB illumination, but serve as DPI indicators. Speaking of DPI, there is a small button just behind this lighting area that by default is configured to cycle between four DPI levels.
At the back of the MM830 is an illuminated Cooler Master logo, which can be customized with Cooler Master’s Portal software.
Taking a look at the left side of the MM830, we see what looks to be a pretty standard layout at first. Sure, we have the aforementioned thumb rest, but other than that it looks pretty standard. However, when you take a closer look you will see that there are four small buttons that are somewhat hidden in the thumb grip, laid out in a d-pad orientation. This layout lets you keep your thumb in one spot and rock it up, down, forward, and back to click the buttons. This is a really cool design, and it ensures that no dust and grime gets stuck in these side buttons. In addition, each of these buttons’ functionality can be customized within the Portal application.
And before we move on, there is one other awesome feature on the left side of the MM830 mouse, and it is a bit hidden as well. You see, behind the glossy plastic in front of the thumb grip, is a small 96 x 24 OLED display. Able to display your own custom images or text, this adjustable screen scrolls the Cooler Master logo and “Make It Yours” by default. Other options include things like your profile, CPU, GPU, and RAM usage, current DPI setting, and others. We will go over this screen a bit more when we take a look at the Portal software.
Moving to the right side of the mouse, we find a very basic side profile. We were actually quite surprised that there is no rubber grip on this side, just the textured plastic body, with a slight curve. While this feels pretty good in our hand, we would have liked to see a bit of grip over here for a bit of added control.
At the front of the MM830 is a standard layout, with a braided cable exiting from between the left and right mouse buttons, and featuring a quite large reinforced rubber sheath for durability.
Flipping the Cooler Master MM830 over reveals a pretty standard undercarriage. Two large PTFE feet, one at the front and one at the back, provide most of the friction reducing capabilities, while a smaller pad under the thumb rest ensures that portion of the mouse doesn’t cause any drag. Centered on the base of the MM830 is an opening that leads to the Pixart 3360 optical sensor, with a range of 100-24,000 DPI. This sensor can be adjusted in 100 DPI increments via the Portal application, and cycling through four preset DPI settings is controlled by the top-mounted DPI button.
