The short version
The MX Master 4 is Logitech's flagship productivity mouse, with an 8,000 DPI Darkfield sensor that tracks on glass, a MagSpeed steel wheel, 8 buttons, haptic feedback and an Actions Ring shortcut overlay in Logi Options+. It connects over Bluetooth or a Logi Bolt receiver and is rated for 70 days per charge. PC Gamer likes the near-silent switches but finds the new features add little over the MX Master 3S, and its 125 Hz polling rules out fast gaming.
Pros
- Very quiet switches suited to shared offices
- MagSpeed wheel scrolls up to 1,000 lines per second
- 8,000 DPI Darkfield tracking including on glass
- Haptic feedback and Actions Ring shortcuts in Logi Options+
Cons
- 125 Hz polling makes it a poor fit for fast gaming
- Heavy at 150 g
- PC Gamer finds the new features add little over the MX Master 3S
Best for
- Office and creative work with heavy scrolling and shortcuts
- Multi-device users who switch between Bluetooth hosts

Common questions
Is the MX Master 4 good for gaming?
PC Gamer says fast-paced gaming is not its strength, and its spec list shows a 125 Hz polling rate, well below the 1,000 Hz or more common on gaming mice.
How does it connect to a computer?
Logitech lists Bluetooth Low Energy and a Logi Bolt USB receiver, and notes compatibility with both USB-A and USB-C receivers, so most desktops and laptops are covered.
