Cooler Master MM-712-KKOH1 MM712 19,000 DPI PixArt Optical ARGB Black Wireless Gaming Mouse

Overall, it's an ok mouse for someone with medium hands. Lightweight and decent for FPS shooters and other games needing a quick response. Ergonomics aren't that great and build quality is so-so. Battery length is good though. However, the biggest issue is after a few months the scroll wheel started to fail. This is a known issue and has no known permanent fix. Google "cooler master mm731 scroll wheel" and you'll see it listed on many forums. I use my scroll wheel often so having it completely fail is a major issue.

Great mouse. Have some issues with the software but it's a great mouse

I love this mouse, my hands are big and the mouse is puny but it disappears in the hand. My favorite mouse ever was the Cooler Master MM710 but once that started double clicking i jumped ship to Razer and got a Razer Viper mini which is awesome but i still missed my mm710... Lo and behold a few years of mild suffering later i see a wireless mm710 with bloody optical switches exists! I was sold instantly.

Yeah i love this mouse, its perfect.
