Logitech MX Master 3S Wireless Mouse Review

What the MX Master 3S Actually Is

The MX Master 3S is Logitech's flagship productivity mouse — a tall, sculpted, right-handed pointer aimed squarely at people who live in spreadsheets, browser tabs, timelines, and code. It's not a gaming mouse and doesn't pretend to be. It's a tool for getting work done without your wrist filing a complaint.

The headline upgrades over the older MX Master 3 are modest but meaningful: near-silent clicks (Logitech claims roughly 90% quieter), and a bumped-up 8,000 DPI sensor that tracks cleanly on glass and other surfaces that wreck cheaper mice. Otherwise, the silhouette and button layout are familiar — which, given how good they already were, is fine.

How It Performs Day to Day

The star is the MagSpeed scroll wheel. Flick it hard and it disengages into a free-spin mode that lets you fly through a thousand-row spreadsheet or a long document in one motion; nudge it gently and it ratchets click-by-click for precision. It's the kind of thing that feels gimmicky for a day and indispensable by week two. There's also a second thumb wheel for horizontal scrolling — a genuine gift if you work in wide timelines or big sheets.

The silent clicks are no joke. They have a soft, muffled thunk instead of a sharp snap, which is a relief in a quiet office, on a call, or next to a sleeping kid. Comfort is excellent over long sessions thanks to the high arch and thumb rest, though the heft (around 140g) and tall shape mean it cradles your hand rather than darting around.

Connectivity is rock solid. It pairs over Bluetooth or Logitech's Bolt USB receiver, remembers up to three devices, and the Flow feature lets you slide your cursor — and even copy-paste files — between two computers. Battery life is the quiet hero: weeks per charge, and a quick USB-C top-up gives you hours from a few minutes plugged in.

The Honest Pros and Cons

Pros: that dual-mode scroll wheel, the satisfying-yet-silent clicks, all-day ergonomics, multi-device switching, fantastic battery life, and customizable buttons via Logitech Options+ software. It tracks on nearly anything, glass included.

Cons: it's big and heavy, so smaller hands and palm-grip purists may find it unwieldy. It's strictly right-handed — lefties are out of luck. The Options+ software is useful but can be naggy with updates. And at this price, it's a premium ask if you just need a basic clicker.

Who Should Buy It (and Who Shouldn't)

Buy it if you spend hours a day navigating documents, code, design files, or massive spreadsheets, value comfort, and want a mouse that disappears into your workflow. Anyone juggling two computers will love Flow alone.

Skip it if you have small hands, you're left-handed, you mainly game (look at a lightweight gaming mouse instead), or you just need a cheap travel mouse. The MX Master 3S is overkill — and overpriced — for casual use.

The Verdict

At roughly $90–$120 on Amazon, the MX Master 3S is one of the most justifiable splurges in tech gadgets for desk-bound professionals. It's not flashy, but it nails the fundamentals — comfort, control, and quiet — better than almost anything else. If your work lives on a screen, your hand will thank you.

Frequently asked questions

Is the Logitech MX Master 3S good for gaming?

Not really. It's heavy, ergonomic, and tuned for productivity rather than the lightweight, fast-response design gamers want. For competitive gaming, choose a dedicated gaming mouse; for work, the MX Master 3S excels.

What's the difference between the MX Master 3 and 3S?

The 3S adds near-silent clicks and a higher 8,000 DPI sensor that tracks better on glass and tricky surfaces. The shape, buttons, and scroll wheels are otherwise the same, so if you already own the 3, the upgrade is minor.

Can the MX Master 3S connect to multiple computers?

Yes. It pairs with up to three devices via Bluetooth or the Logitech Bolt receiver, and the Flow feature lets you move your cursor and copy files between two computers seamlessly.
