A reliable computer mouse remains essential for navigating laptops, mini PCs, and workstations efficiently. The Logitech MX Master series continues to lead in productivity tools, and after extensive testing of previous models like the original MX Master and MX Master 3, the latest MX Master 4, unveiled in October 2025, delivers significant advancements in design and functionality.
Hands-On Experience with the MX Master 4
Testing confirms that the MX Master 4 excels in comfort and performance. Its smooth rubber surface feels inviting under the hand, resists dust and dirt accumulation, and conforms naturally to the grip. Users can expect a full workday without wrist strain or finger fatigue.
The device performs smoothly across diverse surfaces, from thick mouse pads to bare desktops and tabletops. It adjusts quickly and responds precisely, maintaining lightness and agility despite its slightly larger size compared to standard office mice. This compact design saves desk space and travels easily.
Innovative Haptic Feedback
For the first time in the series, the MX Master 4 incorporates haptic feedback via a dedicated thumb pad. This customizable feature enhances interaction during scrolling, selecting, and navigating tasks, providing subtle vibrations for confirmation. Initial encounters may startle users, but it soon integrates seamlessly into workflows.
Actions Ring for Streamlined Control
Another standout addition is the Actions Ring, an overlay interface that maps multiple functions to a single click. It minimizes repetitive actions like menu scrolling, boosting efficiency in office applications. During testing with common software, early enthusiasm led to some unintended activations, prompting a temporary disable. However, it proves valuable for power users seeking to optimize routines.
The MX Master 4 comes in Graphite and Pale Grey worldwide, with Black and Graphite Charcoal options available in North America and Europe. It retails for $119.99 or €129.99, offering strong value for enhanced productivity features.
