Cooler Master MM710 Pro-Grade Mouse Review: Ultralight with Ultraweave
[toc] If there’s one trend in gaming mice today, other than RGB, it’s the ultralight craze. Vendors like Finalmouse have even received the support of big league streamers like Ninja to make their case: the lighter the mouse, the more it feels like an extension of yourself, improving your aim and taking your game to the next level. Finalmouse was renowned for quickly selling out, so it didn’t take long for other companies to step in and fill the void. Enter the Cooler Master MM710 Pro-Grade Gaming Mouse. It features the iconic honeycomb design of an ultralight, a high-quality 16K DPI sensor, a lightweight Ultraweave cable, and a ridiculously low mass of 53-grams sans cable. Is this otherwise simple mouse worth $49.99 and, just as importantly, will it make you a better gamer? Join us as we find out.

Manufacturer Description
“The MM710 is a truly innovative mouse that does more with so much less. Along with all the pro-grade features that make our gaming mice deadly in combat, we’ve also implemented a striking new shell design and a deceptively durable, lightweight Ultraweave cable to trim the overall weight of the mouse to less than 53g. The result is quicker movements, longer gaming sessions, minimal fatigue, and less wrist pain associated with repetitive stress injury.”

Beginning with packaging, Cooler Master keeps it simple. The MM710 arrives in a small and square purple box with a nice product shot and feature call out on the front. Around the rear we have a picture of the bottom of the mouse along with several other feature highlights which we’ll discuss further here.

Inside the box is the mouse itself, some basic documentation on the buttons and warranty, and a set of replacement PTFE feet. This last is a nice addition as users interested in an ultralight competitive gaming mouse are also the most likely to want their feet to be in top condition.

The MM710 is a mid-sized mouse that, size-wise, falls somewhere better the Logitech G502 and G Pro (exact dimensions are: 116.6 x 62.6 x 38.3 mm). This is a wise move as it places it right in the middle between the different grip types. I use a hybrid claw/palm grip and found it quite comfortable, if a bit short. Fingertip users will have no problem using it either as the lightweight and high-quality glide feet allow it to slide like a dream.

The design here is a visually quite interesting. There’s no RGB to speak of (can’t add precious grams for that), but the honeycomb exterior allows you to look right in and see the internals. Honestly, a little lighting probably would have looked pretty slick – just look at the PC Gaming Race Model O. Still, I like the look and think using the Cooler Master logo for the cutouts is a nice touch.

The bigger question with this design is how it will affect the longevity of the mouse. Simply put, mice of this type really haven’t been out long enough to say one way or the other but unless Cooler Master is treating the electronics in some way, they’re exposed to dust, crumbs, and whatever else might fall in there. I didn’t have any issue during a two-week testing phase but in a year from now? I can’t say.

Cooler Master markets the MM710 as an ambidextrous mouse. By sculpt, that makes sense and it’s nice to know that left-handed gamers won’t be left out in the cold. They may be disappointed to see that the Forward and Back buttons on the left hand side aren’t mirrored like the rest of the body, however. At least they’re positioned so they shouldn’t be pressed on accident (often) but they will be more difficult to use. The total button count here is your standard six, but for these users they’ll find it more functional as four.

Under the hood, the mouse uses a premium PixArt 3389 sensor which is well known for its accuracy. Much of a sensor’s quality comes from the firmware and lower quality implementations often reveal themselves in higher DPI settings as filtering systems become apparent and accuracy lessens. Without scientific tools to assess that, I can’t say for certain whether it’s exactly pixel perfect, but I can say that even at about 10K DPI with low in-game sensitivity, the mouse still felt perfectly accurate and like it was tracking me exactly.

The switches are also high-rated OMRONs guaranteed for a lifespan of 20-million clicks. It’s not the highest that OMRON offers (that we typically find at 50M in gaming mice), but it’s certainly acceptable even for heavy-duty use.

Like other Cooler Master Peripherals, the MM710 uses CM’s Portal software for customization. Without RGB, it’s a fairly simple affair of setting DPI stages, polling rate, and click speed, as well as recording/mapping macros. The mouse is able to save up to seven DPI stages progressing all the way to 16K to on-board memory that can then be cycled using the small button below the mouse wheel. Macros are also easy to record and map, though with only six buttons I found them less useful.

Usage Impressions

The question I really wanted to know going in was whether having such a lightweight mouse really made much of a difference for gaming. Fans of these mice are downright ravenous and have a tendency to sell out vendors very quickly. I’m no professional gamer but at that kind of demand, neither can the majority of people buying them be. That said, I do like first-person shooters so I should be right in the middle of the target demographic for a mouse like this.

The answer? Yes and no. I found that I did like having such a lightweight mouse and that the claimed experience is real: the MM710 felt like an extension of my arm more than any other mouse I’ve used. On the other hand, having such a light weight makes it exceptionally fast, so it’s easy to accidentally miss your target when another mouse would have kept more steady. Put another way: there’s a learning curve to such a light mouse.

I did enjoy climbing that curve, though. The mouse buttons have a satisfying click that’s better than even my G502 (one of my favorite mice of all time). Likewise, it feels good to hold and isn’t slippery or prone to showing fingerprints or oils thanks to the matte finish.

On the other hand, the mouse did confirm some of the concerns I had about the honeycomb design. Having all of those holes definitely does make the frame less stable. Squeezing the left side, you don’t feel much movement but it presses in enough to click the Back button. Press it right in the center and it clicks the DPI switch.

That concerns me but it’s very important to draw a line here: those are intentional, harder-than-normal presses that you’re not going to make unless you try. The body is indeed less solid (of course it is) but when used the way it’s designed to be, I don’t think these are issues you’re likely to encounter.


If you’re in the market for an ultralight mouse, the Cooler Master MM710 is one of the most affordable and accessible options available. It’s a simple mouse and didn’t make me a better gamer overnight but it did feel more like an extension of my arm than any other mouse I’ve used. After using it for two weeks, I’m less concerned about the stability of the body than I am the internals being exposed to dust and debris. Only time will tell on that one, but if you don’t need the flash of RGB and don’t want to pay the premium for a Finalmouse, this is a decent option.
