Key Takeaways

Multi-device Flow support is invaluable for developers working across Mac and PC

After switching from a mechanical Ducky keyboard to the MX Keys S, I didn't expect to prefer the membrane feel. But Logitech's scissor-switch design with spherically dished keycaps is genuinely impressive. Perfect for developers who type all day.

Typing Experience

The keys have a satisfying concave dish that guides your fingertips into position. The scissor-switch mechanism provides consistent resistance with a quiet, cushioned bottom-out. It's not as tactile as a good mechanical keyboard, but it's significantly quieter — perfect for open offices or shared workspaces.

Smart Illumination

The backlit keys adjust brightness based on ambient light. The proximity sensors detect your hands approaching and illuminate the keys before you type. This seems gimmicky but genuinely feels magical in practice — especially when working late at night.

Multi-Device Workflow

Pair with up to 3 devices via Bluetooth and switch with dedicated keys (I switch between MacBook, PC desktop, and iPad daily). Combined with the MX Master 3S and Logitech Flow, you can seamlessly move between devices as if they were one — just drag your cursor to the edge of the screen.

Battery Life

With backlighting on, expect about 10 days of full-time use. Turn off backlighting and it lasts months. USB-C charging means you can top up from any laptop charger.
