The Logitech MX Anywhere 3S is the compact sibling of the MX Master 3S: a small, travel-friendly mouse that keeps the premium sensor, quiet clicks and fast-scrolling metal wheel. It’s designed for people who work from laptops in different places — cafés, coworking spaces, trains — and want something better than a trackpad without carrying a full-size mouse. This review covers its features, limitations and who should buy it, based on specifications and widely reported owner experience.
Verdict
Buy it if you want a premium mouse that fits in a laptop sleeve and works on almost any surface, including glass. Skip it if you work at one desk all day with larger hands — the MX Master 3S is more comfortable for long sessions.

What it does well
Works almost anywhere
The Darkfield sensor is the main reason to choose this mouse for travel. Many compact mice fail on glass tables or shiny café counters; the MX Anywhere 3S is built to track on them, so you don’t need to carry a mouse pad.
The MagSpeed wheel
The steel wheel switches between line-by-line scrolling and nearly silent free-spin that flies through long documents, code files and spreadsheets. It’s a feature usually reserved for larger mice.
Quiet and multi-device
Quiet clicks make it suitable for libraries, shared offices and late-night work. Easy-Switch lets you jump between a work laptop, personal laptop and tablet with one button.
Limitations
- Bluetooth only: some corporate PCs block Bluetooth, and older desktops may lack it. The MX Master 3S includes a Logi Bolt receiver; this one doesn’t.
- Small grip: people with large hands often find it cramped for full-day use.
- No thumb wheel: horizontal scrolling requires holding a side button while turning the wheel.
- Not ergonomic: it’s a flat, symmetrical shape. If you have wrist discomfort, look at vertical mice instead.
Who should buy it
- Laptop users who work from multiple locations.
- People with small to medium hands who prefer a compact mouse.
- Anyone who wants MX-level scrolling and tracking in a bag-friendly size.
- Mac and iPad users who switch between devices frequently.
