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.
Ninjutso Sora V2
8 / 10 Expert Rating
An excellent choice for gram-counters, provided you're comfortable with a boutique brand's smaller support network.
