Verdict
Cooler Master MM731
8 / 10 Expert Rating
One of the best value-for-weight wireless mice available; it just lacks the sensor polish of pricier flagships.
Zowie EC2
8 / 10 Expert Rating
A genuine esports classic — proven PMW3360 tracking, a trusted ergonomic shape, and a driverless philosophy that still wins for players who move between systems.
