Logitech MX Master 4 — Hands-on summary and verdict
Logitech’s MX Master 4 arrives as an incremental but meaningful update to the MX Master line. Priced around $120 and shipping in October, it keeps the core strengths of the MX Master 3S while adding a few new tricks aimed at productivity users.
What’s new
- Haptic feedback: A small, customizable haptic motor in the thumb rest provides subtle vibration for confirmations (device switching, Actions Ring, low battery, precise alignment). Adjustable in Logitech Options+ and can be disabled.
- Actions Ring: App-aware overlay for shortcuts, summoned via the side panel with haptic confirmation.
- Finish and durability: The top swaps the older rubbery coating for a lightly textured plastic (thumb rest still rubber). This should reduce peeling complaints from older models.
- Hardware tweaks: Slightly larger/heavier (150 g), USB‑C receiver for Windows, longer horizontal scroll travel, larger PTFE feet, exposed bottom screws for easier recycling, translucent edges, relocated gesture button.
What stayed the same
- Familiar ergonomic shape for right‑handed palm grippers.
- Quiet main buttons and excellent battery life (rated ~70 hours; reviewer saw ~50% after ~1 month).
- 8K DPI sensor and excellent tracking on many surfaces (including glass).
- Three‑device pairing via Bluetooth/Unifying receiver and bottom button.
Minor downsides
- Haptics support is limited at launch — native integrations include Photoshop, Lightroom and Zoom (Premiere arriving soon); system‑level haptics require Options+ to be running.
- No USB‑C cable in the box; polling rate remains at 125Hz (not ideal for super-smooth tracking); Mac version may lack the USB receiver and there’s no dongle storage compartment.
Quick verdict
If you own an MX Master 3 or 3S and are happy with it, the MX Master 4 isn’t a must‑upgrade — it’s an evolutionary refresh. For power users who want the latest productivity features (haptic confirmations, Actions Ring tweaks, improved materials), it’s a compelling choice and likely to be as popular as its predecessors.
