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.
