There is no “perfect” mouse. Even Logitech’s long-rumored MX Master 4 and its tried-and-tested blend of form and function won’t be everybody’s everything. A mouse is merely a computer controller, one that should have enough switches and buttons neatly at your fingertips. The older MX Master mice had most of what any productivity-minded wannabe professional required. The new $120 MX Master 4 has one extra feature with a haptic button that could offer a bounty of extra options. If you already have your necessary keyboard shortcuts etched into your brain like the Ten Commandments carved in slate, you’ll find the rumble in your thumb wholly unnecessary.
Logitech MX Master 4 There aren't so many true upgrades, and the Action Wheel may not be all that, but the MX Master 4 is an excellent successor to the best-feeling wireless work mouse. 4.5 Pros Excellent ergonomic feel
Satifsfying haptics
Free-spinning and side scroll wheels
Works on almost everything
Action Wheel has surprising use cases Cons Not enough apps for Action Wheel
No compartment for Bolt receiver
Bigger and heavier than ever
The design for Logitech’s “perfect” mouse didn’t need to change. If you’re a proud user of a Logitech MX Master 3 or 3S (the latter retailed for $100 in 2023), and you haven’t worn away the silicone thumbrest with your affections, you don’t need another mouse. Then again, the new MX Master 4 is so nice, so precise, and so feature-rich, I can’t think of another mouse I’d rather drag my cursor around with. The smooth operation on my desk, combined with the near-silent clicks and free-spinning magnetic aluminum scroll wheel, feels as satisfying as it ever did. You simply can’t expect any real upgrades from this mouse. Even with haptics and software features, the MX Master 4 will still be a companion that’s so thick and heavy it will rarely, if ever, leave your desk.
