Logitech MX Master 4 review: the productivity mouse gets haptics and an Actions Ring

The MX Master series has been the default choice for people who spend all day at a computer, and the MX Master 4, launched in autumn 2025, is still Logitech's flagship productivity mouse in 2026. It succeeds the hugely popular MX Master 3S with a new haptic thumb panel, a shortcut menu called the Actions Ring, and a redesigned, more durable shell.

This review is based on Logitech's specifications, independent reviews and owner feedback. Put simply, the MX Master 4 is an excellent mouse, but it is an evolution rather than a revolution.

Design and ergonomics

The sculpted, right-handed shape keeps your wrist at a relaxed angle, with a deep thumb rest and long primary buttons. Reviewers, including one with joint pain who normally prefers vertical mice, report comfortable all-day use.

The biggest physical change is the finish. The soft rubber coating of the 3S, which can turn sticky after years of use, is replaced by hard plastic with frosted and finely textured areas. It should age better, and it contains more recycled plastic, though some users find it less cosy in the hand. The mouse is a few millimetres larger and about 9g heavier than the 3S, which matters mostly to people with small hands. Colours are Graphite and Pale Gray, with a Mac version in Space Black or White Silver.

PTFE feet glide smoothly on desks and mouse pads. The mouse is weighty enough to feel planted, which many productivity users prefer over ultralight gaming mice.

Haptic Sense Panel and Actions Ring

The gesture button of the 3S is replaced by a touch-sensitive panel in the thumb area. Pressing it opens the Actions Ring, an on-screen radial menu with up to eight shortcuts, such as switching apps, locking the screen or running tools in creative software. Unlike memorised gestures, everything is visible, so it is easier to learn. Logitech's own study claims it can save up to 33% of time on common tasks, though results depend on your setup.

The panel also provides haptic feedback for actions such as snapping objects to grids, notifications and slider adjustments, and it integrates natively with Advanced Haptics in Windows 11. Reviewers like the sensation but describe it as a nice extra rather than a reason to buy. Intensity is adjustable, and turning it down saves battery.

Buttons, scrolling and tracking

An extra thumb button brings more programmable controls than the 3S. The steel MagSpeed wheel switches between precise ratchet scrolling and a free-spinning mode that can fly through about 1,000 lines per second, which is ideal for long documents and spreadsheets. A side thumb wheel handles horizontal scrolling in timelines and wide sheets.

The 8,000 DPI sensor tracks on nearly any surface, including glass at least 4mm thick. Clicks are quiet, which suits shared offices. It handles casual gaming well over the 2.4GHz receiver, but it is not a dedicated gaming mouse.

Per-app profiles are where the MX Master 4 shines. You can map the thumb buttons to undo and redo in design apps, to tab switching in browsers, and to push-to-talk or mute in video calls, and the mouse switches profiles automatically as you change apps.

• Actions Ring: up to 8 shortcuts
• Extra programmable thumb button
• MagSpeed wheel: ratchet and hyper-fast modes
• Horizontal thumb wheel
• Quiet clicks

Connectivity and software

You can pair up to three devices, one over the Logi Bolt receiver and two over Bluetooth, and switch between them with a button. Logitech says connectivity is twice as strong as before. The Logi Options+ app for Windows and macOS lets you set per-app button maps, customise the Actions Ring, adjust haptics and install plugins for third-party apps. Basic functions work on Linux, ChromeOS and iPadOS without the app.

MX Master 4 battery life

The battery grows to 650mAh from 500mAh, but the haptics use extra power, so Logitech's rated battery life stays at around 70 days on a full charge, the same as the 3S. Real-world reports suggest two to four weeks between charges for heavy daily users, and quick top-ups via USB-C get you going again fast.

Logitech Flow, available through Logi Options+, lets you move the cursor and even copy files between two computers on the same network, which pairs nicely with the three-device switching.

MX Master 4 vs MX Master 3S

The 3S has the same sensor, a similar shape and the same MagSpeed wheel, plus a soft-touch finish that some prefer. The 4 adds the Actions Ring, haptics, an extra button, better connectivity and a more durable shell. For newcomers, the MX Master 4 is the better buy. For 3S owners, the upgrade is optional unless the old coating has worn or you want the Actions Ring.

Is the Logitech MX Master 4 worth it?

If you work long hours with spreadsheets, code, design tools or many browser tabs, the MX Master 4 is worth the money. Its comfort and customisation save time and strain every day. If you have small hands, are left-handed or are on a tight budget, look at the alternatives below.

Frequently asked questions

The Logitech MX Master 4 refines a near-perfect formula. Its comfortable shape, clever Actions Ring, excellent scrolling and multi-device support make it the productivity mouse to beat in 2026. The haptics are more fun than essential and 3S owners can wait, but anyone buying a new work mouse should put this at the top of the list.
