Logitech announced the MX Master 4 mouse a couple of months ago, and so far, it has been available at its quite steep MSRP of $119.99, which is $20 more than the previous MX Master 3S model. However, right as we entered 2026, Logitech discounted its flagship mouse, allowing you to save up to 11% and get this mouse for $106.99.
There are several improvements you get with the MX Master 4. For one, the mouse is now made of a better material with significantly improved longevity. As such, Logitech addressed one of the biggest complaints about the previous-gen MX Master models. It also equipped the mouse with a haptic feedback button that lets you invoke the Action Ring or map it to five various gestures.
The mouse comes with a USB Type-C Logi Bolt connector (the Mac version comes without it and has slightly different colors), and has better access to the internals thanks to exposed screws at the bottom, which is better for service and repairs. Like the MX Master 3S, it has an 8K sensor, silent switches, the MagScroll wheel, and an extra wheel for horizontal scroll, and plenty of customizable buttons that you can remap in the Logitech Options+ app on Windows and Mac.
