Logitech MX Master 4
The MX Master 4 keeps what made the series a default recommendation — the MagSpeed wheel, long battery life, three-device switching — and adds haptic feedback and an Actions Ring. Reviewers call it an evolution, not a revolution, and it’s heavy at 150 g.
- MagSpeed scroll wheel is brilliant
- Exceptional battery life
- Heavy
- Thumb wheel lacks MagSpeed functionality and feels cheap
