Logitech has officially launched the latest version of its popular productivity mouse, the MX Master 4. We’ve been able to use it for the past few weeks, so here are our hands-on impressions.
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.
For the most part, this is an iterative update, with the same general shape, battery life, 8K DPI sensor and ultra-quiet clicks as the MX Master 3S before it. It is a touch heavier (150 grams vs. 141g), wider (3.48 inches vs 3.32 in.) and taller (5.05 inches vs. 4.92 in.) than the last model, but if you found the 3S or older MX Master 3 comfortable, you should have few issues here. That said, it’s still a hefty mouse designed for palm grippers and right-handed users: Its gentle contours, generous hump, ample thumb rest and large buttons will fit like a glove if that describes you, but lefties and those with especially petite hands won’t agree.
The flashiest change here is the addition of haptic feedback, which is built into a small panel within the mouse’s thumb rest. You can customize the intensity of this effect through Logitech’s Options+ software — or turn it off entirely — but it essentially brings a modicum of smartphone-style feedback to your desktop. When you first pair the mouse, for one, you’ll feel a little bump. The same goes if you move between devices using Logitech’s “Flow” feature. When battery is low, it’ll vibrate. If you’re trying to precisely line up a graphic in an app like Photoshop, you’ll get a little buzz when you’ve moved it to the exact right spot.
