Coolermaster MM731 Preview – A Wireless ~60g Ergo

The good folks over at Hardware Canucks has given us our first glimpse at the first lightweight Cooler Master mouse, the MM731. It’s a wireless medium sized ergo mouse that can utilize both 2.4 GHz and Bluetooth.  Most impressively, the mouse is under ~60g. It features optical switches, USB-C, PTFE feet. No exact dimensions or retail price has yet been announced but stay tuned as we should expect to see lots of information dropping soon on the mouse. The one caveat about the mouse so far is the unconventional sensor position which is close to the front of the mouse, time will tell if this is an issue in actual use.

Cooler Master has posted up a description of the mouse themselves stating.

The MM731 retains the spirit of the our honeycomb MM710 series while staying true to the classics. Each feature is intended to give you lightspeed responsiveness: PTFE feet, hybrid wireless for supreme versatility, a 19,000DPI optical sensor, and optical switches for durability and input. Put that in a new ergonomic shell that reduces the weight to <60g without having exterior holes, and the MM731 truly is less than the sum of its parts. The great news is that the retail price of $89.99 will put it in line with other budget wireless options on the market.
