Logitech MX Master 3S Review (2026)
In-depth review of the Logitech MX Master 3S: 8K sensor, MagSpeed scroll, quiet clicks, and multi-device flow. Research-based assessment.
Logitech MX Master 3S
The productivity standard, now quieter and sharper.
Our verdict
The MX Master 3S is the best productivity mouse you can buy. The 8K Darkfield sensor tracks on glass, the MagSpeed wheel is still unmatched for long documents, quiet clicks make it office-safe, and Flow lets you move between three computers. It is not a vertical mouse and it is not for gaming, but for desk work it has no real rival.
What we like
- 8K DPI sensor tracks on glass
- MagSpeed electromagnetic scroll wheel
- Quiet clicks and multi-device flow
What to watch out for
- Not a vertical design, so wrist stays pronated
- Heavier than basic mice
- Priced above simpler ergonomic options
Who it is for
Office workers, programmers, designers, and anyone who lives in documents and browsers and wants the most capable comfortable mouse available.
Design and comfort
The 3S keeps the sculpted right-handed shape of the MX line: a thumb rest with gesture button, two side buttons, and a secondary horizontal scroll wheel. The body supports the full hand so fingers rest rather than grip. Quiet click switches cut the click noise dramatically compared to the older 3, which matters in open offices. At around 141 grams it is heavier than basic mice, but the weight feels planted rather than tiring during normal desk use.
Sensor and scroll performance
The 8K DPI Darkfield sensor is the headline upgrade: it tracks reliably on glass, which the old sensor could not do. For most users 8K DPI is overkill, but the headroom means flawless tracking at normal speeds. The MagSpeed electromagnetic wheel remains the best scroll wheel made: it spins freely through thousand-line documents and ratchets precisely for line-by-line work, switching modes automatically. App-specific button customization through Logi Options+ is deep without being fiddly.
Connectivity and battery
Bluetooth and Logi Bolt cover three devices with easy switching, and Logitech Flow moves the cursor and files between computers on the same network. USB-C charging gives a full day of use from a one-minute charge, with up to 70 days per full charge. The main gap is the lack of a vertical variant; wrist-pronation relief is not what this mouse is for.

Questions, answered
Is the MX Master 3S worth it over the older MX Master 3?
The 3S upgrades the sensor to 8K DPI with glass tracking and switches to quiet clicks. If you use a glass desk or work in a quiet office, the upgrade is meaningful. Otherwise the older model remains very capable.
Does the MX Master 3S work on Mac?
Yes, it pairs over Bluetooth and Logi Options+ supports macOS with gesture and app-specific customization. Some Windows-specific shortcuts do not translate, but core function is full.
Can I use the MX Master 3S for gaming?
Casual gaming is fine, but it is not a gaming mouse: it is heavy, the polling rate is standard, and the shape prioritizes comfort over flick shots. Competitive players should buy a gaming mouse.
