Logitech MX Anywhere 3S: Specs, Features, Pros & Cons
The travel half of Logitech's MX family, and its brief has not changed in a decade: a mouse small enough to vanish into a laptop sleeve that gives up as little as possible to the full-size MX Master on the way in.
This revision quietly fixed the two things worth fixing — tracking on effectively any surface including glass, and clicks re-engineered to be genuinely quiet, a real courtesy on a plane or in a meeting. The wheel remains the feature MX owners cannot go back from.

Editor’s note
The MX Anywhere 3S is the travel half of Logitech's MX family, and its brief has not changed in a decade: a mouse small enough to vanish into a laptop sleeve that gives up as little as possible to the full-size MX Master on the way in. This S revision quietly fixed the two things worth fixing – the sensor now tracks at up to 8,000 DPI on effectively any surface including glass, and the main clicks were re-engineered to be genuinely quiet, a real courtesy in libraries, planes and meetings.
The signature hardware remains the MagSpeed wheel: ratcheted for precision until a flick spins it free through a thousand lines a second, shifting between modes automatically. It is the feature MX owners cannot go back from. Six programmable buttons, Logi Options+ profiles that follow you between apps, and multi-device switching across three machines complete the workflow story. Battery life is rated at seventy days, topped up over USB-C – and a one-minute charge buys three hours, which in practice means the battery is never actually a problem.
The honest limitations: at 100.5 millimetres it is genuinely small, and large hands will claw uncomfortably through long sessions – this is a travel shape, not an all-day throne. There is no receiver in the box; the 3S connects over Bluetooth, with Logitech's Bolt dongle sold separately – the same quiet unbundling Logitech's K980 keyboard pulls. And Logitech publishes no polling rate, which tells you correctly that this is not a gaming mouse.
At $89.99 list and frequent discounts, the buying logic is simple: if the mouse lives in a bag, this is the default answer. If it lives on one desk, the full-size MX Master is more comfortable for the same money.

The bottom line
The Logitech MX Anywhere 3S earns a VS Score of 40, trailing most of the 70 mice we compare here, at least on the spec sheet.
- Who it’s for
- Laptop-bag workflows: the small MX with 8K any-surface tracking, quiet clicks, the MagSpeed wheel and 70-day battery – the default travel mouse.
- Who should look elsewhere
- Large hands over long sessions, gamers (no published polling rate), and anyone expecting a receiver – Bluetooth only in the box, Bolt sold separately.
- The trade-off that matters
- You accept the compact claw-grip shape and dongle unbundling for MX-class features that actually fit in a sleeve pocket.
- The main alternative
- Logitech's full-size MX Master line is the same money and far more comfortable if the mouse never leaves the desk.
