Logitech MX Master 4 Wireless Mouse

MX Master 4 Wireless Mouse

Fewer movements to reach the same tools

The Actions Ring is a customisable overlay that appears at your cursor, putting your most-used tools, filters and shortcuts where your hand already is instead of at the edge of the screen. Logitech’s own Ergo Lab study puts the reduction in repetitive mouse movement at up to 63%, and time saved at up to 33%. Those figures come from a 2025 study of 37 MX Master users across eight desktop actions, so treat them as directional rather than guaranteed, but the mechanism is sound: shortcuts at the cursor mean fewer traverses across the screen.

Haptic feedback that reduces the need to look

The Haptic Sense panel delivers a subtle vibration when you navigate the Actions Ring, trigger a Smart Action or complete a gesture. Feedback through the fingertips means less visual checking and less over-correction, which matters most in precision work like editing, design and data analysis. Intensity is adjustable across four levels in Logi Options+, or switched off entirely.

A scroll wheel that clears documents in a flick

The MagSpeed wheel moves 1,000 lines per second and stops on a pixel. Smart shift switches between ratcheted precision and free spin automatically, so long spreadsheets and documents take one movement rather than dozens of finger repetitions. A separate thumb wheel handles horizontal scrolling without twisting the wrist.

A shape that supports the hand rather than holding it up

The sculpted body and thumb rest keep the hand supported through its natural tilt, so the palm rests rather than hovers. Eight buttons, a gesture button and adjustable DPI from 200 to 8,000 in 50 DPI steps mean less hand travel to cover the same screen, and tracking works on any surface including glass.

Set up once, then forget it

Up to 70 days on a full charge. Connect via Bluetooth Low Energy 5.1 with a 10 m range, backed by 2x stronger connectivity from an upgraded radio chip and antenna placement.

Two finishes, same mouse

Pale Grey and Graphite are identical in every specification. Choose on the basis of your desk, not your workflow.

The result: the same work done with fewer hand movements, less screen-crossing and less visual over-correction. The strain reduction here isn’t postural. It’s volumetric.
