About this item

Product details

The fourth MX Master keeps the tall, thumb-rested shape that made the line a fixture on desks, and adds a haptic motor underneath it. The motor fires when you land on an item in the Actions Ring, cross a gesture edge or step the DPI, so a shortcut registers through your hand rather than only on screen.

The rest is familiar in the best way. An 8K DPI Darkfield sensor still tracks on glass, the machined MagSpeed wheel still flips from ratcheted steps to a free spin, and the primary buttons keep the quiet click. Charging is USB-C.

Sold and shipped by ComBuy. Free shipping on orders over $35.

8K DPI Darkfield sensor tracks on glass and other surfaces that defeat optical mice
MagSpeed steel wheel switches between ratcheted precision and a free spin down a long page
Pairs with three machines over Bluetooth or the Logi Bolt receiver, with Flow between them
USB-C charging gives about 70 days of use, or three hours from a one-minute top-up

Questions & answers

What does the haptic feedback actually do?

It is a short vibration under the thumb that marks an event: landing on an Actions Ring item, hitting a gesture edge, switching DPI or reaching a scroll limit. Intensity is adjustable, and it can be turned off.

Do I need Logi Options+ installed?

The mouse tracks, clicks and scrolls without it. The Actions Ring, per-app button remaps, haptic settings and Flow all live in Options+, so most of what makes this model different needs the software.

Can I use it with a laptop and a desktop at the same time?

Yes. It holds three pairings and swaps between them from a button underneath. With Flow enabled, moving the cursor past the edge of one screen hands control to the next machine and carries the clipboard across.

Does it work on a glass desk?

Yes. The Darkfield sensor is designed for glass and other reflective surfaces, down to about 4mm thickness, where a standard optical sensor stutters or stops.

Is a USB receiver included?

A Logi Bolt USB-C receiver is in the box for machines where Bluetooth is unreliable or unavailable. Bluetooth Low Energy pairing works without it on Windows, macOS, ChromeOS, Linux and iPadOS.
