Summary
The undisputed productivity mouse champion, praised by experts and Reddit alike. Silent clicks, an 8,000 DPI sensor that works on glass, and multi-device support make it the go-to for anyone who spends serious time at a desk.
The only mouse to earn a perfect 5-star rating from PCMag in 2026, the MX Master 4 adds haptic feedback, a new gesture button, and an Action Ring to an already near-perfect formula. The top ergonomic pick across multiple expert review sites.

Our take
If you work at a computer all day and want one mouse that does everything brilliantly, buy the MX Master 3S and stop looking. It's the rare product that earns a 5-star rating from reviewers AND constant Reddit love simultaneously.
If you're upgrading from the MX Master 3S, the 4 is worth it for the haptic scroll wheel and gesture controls alone. This is the mouse for professionals who want their hardware to work as hard as they do.
