Should you buy it?
Buy the MX Master 4 if you want the most capable office mouse: reviewers praised its excellent ergonomics and build, a superb adjustable scroll wheel, near-silent main clicks, a new gesture button and Action Ring shortcuts, deep customization, multi-device connectivity and very long battery life. Skip it if you're left-handed or want a light mouse for fast gaming, because it's right-handed only and heavy. Several reviewers found the haptics gimmicky, and there's still nowhere to store the USB receiver.
Professionals and power users who want a customizable desk mouse.
Left-handed users and competitive gamers.
