Editor’s note (11/10/25): After spending another month with the MX Master 4, our impressions remain largely unchanged. The new textured plastic finish and silicone thumb rest have shown no signs of wear, and we’ve continued to see no erratic behavior with the electromagnetic scroll wheel. Battery life still lines up with Logitech’s rating, while the haptic feedback and Actions Ring functionality remain useful if inessential. We’ve added an official review score to this post as a result. Our original hands-on is below.
Original post (9/30/25): If you’ve shopped around for a wireless mouse at any point in the past decade, you’ve probably seen lots of people recommending a Logitech MX Master. There’s good reason for that: They aren’t cheap, but they’re usually comfortable, versatile and loaded with features designed to make working in front of a monitor all day a little less annoying. The current MX Master 3S has sat at the top of our own wireless mouse buying guide for some time now.
Now, three years after releasing the 3S, Logitech is rolling out the new MX Master 4, which costs $120 and will ship in October. I’ve been able to test it out for the past few weeks.
