The Logitech MX Master 3S has been the default recommendation for office workers, designers, and developers since it launched, and for good reason. After using it daily for a month alongside a MacBook Pro and a Windows desktop, we can confirm: it's still the productivity mouse to beat.

Ergonomics & Build

The sculpted shape supports your hand without forcing a grip, and at 141g it's heavy enough to feel planted but light enough for extended use. The thumb rest, textured side grip, and the machined scroll wheel all feel premium. The USB-C charging port means a 1-minute charge gives 3 hours of use, and a full charge lasts up to 70 days.

The Scroll Wheel Is the Star

The MagSpeed electromagnetic wheel is the best scroll wheel ever made. Flick it and it free-spins through thousands of lines; click it and it switches to precise ratcheted scrolling. The side buttons — forward, back, and gesture — are all remappable, and the thumb wheel adds horizontal scrolling that's invaluable for timelines and spreadsheets.

Silent Clicks & Sensor

The 3S upgrades to quiet clicks — about 90% quieter than the MX Master 3 — which matters in shared offices and open-plan environments. The 8K DPI sensor tracks on any surface, including glass, and Logitech's Darkfield technology means you'll never need a mouse pad again.

It connects to three devices simultaneously via Bluetooth or the Logi Bolt USB receiver, and Logitech's Flow feature lets you copy-paste and drag files between computers as if they were one machine. The MX Master 3S works seamlessly with both macOS and Windows — rare for a peripheral.

The Verdict

The MX Master 3S remains the best productivity mouse you can buy. It's comfortable for 10-hour days, the battery lasts months, and the customization options via Logi Options+ are deep. Gamers should look elsewhere (it's not built for fast FPS play), but for everyone who works on a computer for a living, it's the gold standard.
