Dell MS3320W
Score: 91/100Rankings
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 Dell Mobile Wireless Mouse MS3320W offers exceptional battery longevity and dual-mode connectivity in an ambidextrous package, but its plastic build, lack of side buttons, and limited sensor performance keep it from appealing to power users.
