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.
Razer Orochi V2
7 / 10 Expert Rating
Not a performance flagship, but the best choice for anyone who wants to forget about charging a mouse for months at a time.
