Our rating of the Cooler Master MM731 (8/10): one of the best value-for-weight wireless mice available; it just lacks the sensor polish of pricier flagships. Our rating of the SteelSeries Rival 3 (8/10): the best budget mechanical-switch mouse in SteelSeries' lineup, and a fair pick for anyone who doesn't need a flagship sensor.
