Is the MX Keys S combo worth it over buying the keyboard and mouse separately?

The combo usually costs less than the two devices bought alone and includes one Logi Bolt receiver for both. If you only need one of the two, buy that piece by itself.

Can I use the keyboard and mouse with a Mac and a Windows PC at the same time?

Yes. Each device pairs with up to three computers over Bluetooth or the receiver, and you switch with a key or the button under the mouse. Logitech Flow can move the cursor between machines on the same network.

How long does the battery last?

Logitech rates the keyboard at up to 10 days with backlighting on, or about 5 months with it off, and the mouse at up to 70 days. Both charge over USB-C.

Does the keyboard work with Linux and Chrome OS?

Yes, both are listed as supported. Basic typing and pointing work over Bluetooth, but Logi Options+ customization is limited on Linux.

You get the MX Keys S keyboard, the MX Master 3S mouse, a Logi Bolt USB receiver, a USB-C charging cable and documentation.

When is the best time to buy it?

The set has sold around $119.99 to $170 recently, and $119.99 at Best Buy as of November 5, 2026 is near the low end. Holiday sales and back-to-school periods are the usual times for deeper discounts.
