Score: 93/100Rankings

The Kensington Pro Fit Full-Size Wireless Mouse delivers a comfortable, ergonomic experience for right-handed users with reliable 2.4 GHz connectivity and a lifetime warranty, though it lacks button programmability and has occasional scroll-wheel quirks.

The SteelSeries Prime is a wired esports-grade mouse featuring the industry-leading TrueMove Pro sensor, magnetic optical switches and on-board customization. At 68 g it balances lightweight feel with a textured ergonomic shape, but its wired nature and heavyweight software may deter some users.
