The Logitech MX Master 4 is a flagship wireless mouse with customizable haptic feedback and an on-screen Actions Ring for quick shortcuts. It builds on the MX Master 3S with a new Haptic Sense Panel, 8K DPI tracking on glass, and improved connectivity. Reviewers praise its comfort and build quality, but some find the haptics gimmicky and the mouse heavy for travel. It suits power users and creatives who want deep customization and ergonomic support.

Reviewers and owners praise the MX Master 4 for its comfortable ergonomic design, precise tracking, and the productivity boost from the Actions Ring. The haptic feedback divides opinion: some find it useful, others see it as a gimmick. Complaints focus on the mouse's weight and the need for software to unlock key features.
The Logitech MX Master 4 is a wireless mouse with a Haptic Sense Panel that gives customizable haptic feedback for specific actions, shortcuts and notifications. You can feel image snapping onto grids, desktop switching, slider adjustments and notifications. Feedback type and intensity are set in the Logi Options+ app, which also supports plugins for third-party apps. The app is available for Windows and macOS.
The Actions Ring brings favorite tools, shortcuts and actions to the cursor, so there is less searching through menus. Shortcuts can be personalized in Logi Options+. In a Logitech Ergo Lab study (2025) with 37 MX Master users across 8 desktop actions, the Actions Ring saved up to 33% of time and reduced mouse movement by up to 63%. Results vary with the assigned shortcuts.
The MagSpeed scroll wheel is machined steel and switches between ratchet mode and a hyper-fast mode that scrolls 1,000 lines per second. An 8,000 DPI sensor tracks on nearly any surface, including glass at least 4 mm thick. A tilted shape and the placement of the buttons are meant to keep the arm in a more natural posture, and the scroll wheel follows the natural movement of the thumb for horizontal navigation. Quiet Click buttons produce 90% less click noise than the MX Master 3.
