The wait is over. Logitech has just released a new version of its flagship productivity mouse and it’s called the MX Master 4.
The MX Master 4 is the successor to the extremely capable MX Master 3S. The MX Master 3S was a mouse I loved so much that I called it “the king of productivity mice”. So what has Logitech done to improve it?
The two headline new features are haptic feedback and the Actions Ring. The MX Master 4 now has a haptic motor that subtly vibrates the mouse when performing specific cations and shortcuts. This provides feedback to a user, letting them know their inputs have been registered.
