Verdict
Cooler Master MM720
8 / 10 Expert Rating
One of the lightest wired mice on the market, backed by a genuinely flagship sensor rather than budget internals.
SteelSeries Rival 3
8 / 10 Expert Rating
The best budget mechanical-switch mouse in SteelSeries' lineup, and a fair pick for anyone who doesn't need a flagship sensor.
