Logitech MX Master 3S (Graphite) Review

What the MX Master 3S actually is

This is Logitech's flagship productivity mouse, and the 3S is a refinement of the already-loved MX Master 3 rather than a reinvention. The two big changes over the older model: clicks are roughly 90% quieter, and the sensor jumps to 8,000 DPI so it tracks cleanly on glass and other surfaces that used to confuse it.

It's a chunky, right-handed mouse built for people who live in spreadsheets, code editors, timelines, and giant browser tabs. The Graphite version is the safe, classic look. You get Bluetooth plus Logitech's Bolt USB receiver, and it pairs with up to three devices you can swap between with a button on the bottom.

How it performs day to day

The headline feature is the MagSpeed scroll wheel. Flick it hard and it switches from notched, line-by-line scrolling to a near-frictionless free spin that'll send you down a thousand rows in a second. It's genuinely useful, not a gimmick, and once you've used it, regular mouse wheels feel like dial-up.

The silent clicks are the quiet hero. Same satisfying feel as a normal click, almost none of the noise, which matters in shared offices, on calls, or in a quiet house at 11pm. There's also a thumb wheel for horizontal scrolling and a hidden gesture button under the thumb that, once you map it in Logitech Options+, becomes weirdly hard to give up.

Battery life is a non-issue. Logitech rates it at around 70 days on a full charge, and a quick minute on USB-C buys you hours. It charges while you keep working, so you basically never think about it. The Options+ software lets you set app-specific button profiles, which is where power users get their money's worth.

The good and the not-so-good

Pros: top-tier ergonomics for long sessions, that brilliant scroll wheel, near-silent clicks, multi-device switching, excellent battery, and tracking on almost any surface. It's the mouse most reviewers and owners point to when someone asks what to buy for work.

Cons: it's big and shaped for right hands only, so lefties and small-handed users are out of luck. It's heavy at around 141 grams, and the Options+ software, while powerful, can be naggy and occasionally flaky. It's also not a gaming mouse. The sensor is fine but the weight and shape aren't built for twitchy aim, so competitive players should look elsewhere.

Who should buy it, who should skip it

Buy it if you spend your day working and want the most comfortable, capable productivity mouse without overthinking it. People juggling a laptop and a desktop will love the multi-device switching. Anyone tired of clicky noise on video calls will notice the silence within an hour.

Skip it if you're left-handed, have small hands, or mainly game. And if you already own the original MX Master 3 and don't care about quieter clicks or glass tracking, the upgrade is minor. Save your money. For a cheaper Logitech option with most of the comfort, the MX Anywhere 3S is smaller and travel-friendly.

The verdict

The MX Master 3S earns its reputation. In the rough $80 to $100 range it's not cheap, but it's the kind of tech gadget that quietly improves every working day and lasts for years. For most desk workers, this is the easy recommendation.

Frequently asked questions

Is the MX Master 3S worth upgrading from the MX Master 3?

Only if you want the quieter clicks or need tracking on glass and shiny surfaces. The shape, scroll wheel, and battery are basically the same, so most existing MX Master 3 owners can skip it.

Does the MX Master 3S work with Mac and Windows?

Yes. It works with Windows, macOS, Linux, ChromeOS, and even iPadOS over Bluetooth. Logitech's Options+ software is available for Mac and Windows to customize buttons and set per-app profiles.

Is the MX Master 3S good for gaming?

Not really. It's a productivity mouse with a heavier body and a shape built for comfort, not fast aiming. For gaming, look at a dedicated lightweight gaming mouse instead.
