Logitech has unveiled the MX Master 4, the successor to the popular MX Master 3S mouse, featuring haptic feedback and an "Action Ring" menu for quick access to tasks.

The mouse includes customizable shortcuts and improved connectivity, with an 8K DPI sensor and dual-mode scroll wheel. Despite being heavier than its predecessor, the MX Master 4 offers enhanced productivity features and customization options. Priced at $119.99, it will be available in multiple color options.
