COOLER MASTER MM712 in test – The VW Golf among anorectic wireless mice?

Ergonomics and battery life

Similar to the recently reviewed Corsair Katar Elite, the similarly sized MM712 is aimed at players with a palm or claw grip – primarily for players with smaller hands. Because the MM712 is slightly narrower at the top and slightly wider at the bottom, it feels more comfortable in my hand than the Corsair and also offers a better grip due to the rougher surface. Visually, the Qatar Elite looks a bit more sophisticated with its different surfaces and the visible DPI indicator LED.

With relatively small hands for my height, my fingertips (palm grip) are already almost at the front end of the primary keys, but not yet alarmingly far forward. I can comfortably reach the shoulder buttons with my thumb.

I had the MM712 in use for a test period of almost 30 hours (2.4GHz with 1000Hz interrogation rate and activated logo illumination) and the battery level indicator still showed “medium”. Unfortunately, I could not judge whether it really achieves the stated battery runtime of just under 80 or 180 hours (2.4 GHz / Bluetooth) during the test period.

 

Productivity / Drawing

I came up with something for the practical test a few reviews ago, which was not very well received by many readers. I had “painted” some shapes in MS Paint, described my impressions of them, and included the resulting image in the review. I understand the criticism that this methodology is not really comprehensible, but I consider the test itself to be quite meaningful – at least if you had the mouse in your hand during it. That’s why I stuck with the methodology until I came up with something more comprehensible. I continue to take suggestions from the community in this regard.

While doodling in Paint, I got some meaningful impressions again. With its light weight, excellent gliding PTFE feet and no annoying cable, the MM712 is very smooth to maneuver over the mouse pad. When drawing, however, you notice that the precision of the PixArt sensor used cannot quite keep up with that of the Corsair Marksman sensor. Especially small circular movements are not implemented quite as cleanly as with the 26k DPI sensor with hyperpolling.

 

Gaming / CS:GO

In the usual CS:GO botmatch, I liked the handling of the MM712 immensely. The compact mouse fits well in the hand, offers a very good grip and glides over the mouse pad almost without resistance. Cooler Master has also managed the balance extremely well – when I push the mouse over the mouse pad, neither the front nor the rear swing around, which speaks for excellent balancing.

In terms of precision, however, I also missed the noticeably finer-resolution Marksman sensor a bit when aiming in CS:GO. Especially with small circular movements (as with the spiral in the paint test), the higher query rate is definitely noticeable.

 

Interim summary

Overall, the PixArt sensor used reminded me a lot of the one used in the Roccat Kone XP, and as research revealed, the Owl Eye sensor in the Roccat mouse is actually based exactly on the PAW3370 used in the MM712. In summary: Very high level, but not quite top notch.

 

Soundcheck

At the end still the obligatory sound check. In terms of processing, there is nothing. The buttons function impeccably and provide decent haptic feedback. Of course, the acoustic feedback can only be described to a limited extent, so a few recordings as usual.
