The MX Keys line has been a consistent recommendation across productivity and tech review outlets for years, and the MX Keys S refines it further with smart backlighting that reacts to your hands approaching and adjusts to ambient light automatically.

What Owners Actually Say
Owners upgrading from older Logitech keyboards describe a smooth transition. One reviewer whose previous MX Master lasted “4.5 years” before individual keys wore out replaced it without hesitation, praising the “smooth, quiet typing and scrolling experience” and easy Bluetooth pairing. Another highlighted the flexibility of the connection options: “when it dies, just plug it in and it is a wired keyboard,” and liked the multi-device switching across Logi dongles and Bluetooth.
Layout changes are the most repeated frustration for long-time Logitech users — one reviewer was upset that the dedicated Print Screen key was removed in favor of a snip-tool button, and the Function keys are grouped differently than on older models. A smaller number of owners reported a squeaking sound developing near the Enter and Backspace keys after weeks of use. If you rely on specific legacy keys or shortcuts, it’s worth checking the current key layout against your workflow before switching over.
Pros
- Smart backlighting activates as your hands approach and adjusts brightness to the room automatically
- Switches between up to 3 paired devices (computer, tablet, phone) with a single button press
- Low-profile spherically-dished keys reviewers describe as quiet and comfortable for all-day typing
- USB-C rechargeable with reviewers reporting roughly 10 days of battery life with backlighting on
Cons
- Noticeably more expensive than basic wireless keyboards that only offer single-device pairing
- No numpad on the standard layout — a full-size version is sold separately
FAQ
Does it work with both Mac and Windows?
Yes — it ships with an OS-switch key and works across Windows, macOS, Linux, iOS, and Android via Bluetooth or the included USB receiver.
Is it worth the upgrade from the original MX Keys?
If you already own the original MX Keys, the S mainly adds slightly better key feel and marginally improved backlighting logic — not essential, but a easy pick if buying new.
