Enjoy smooth, precise, and comfortable typing experiences with the MX Mechanical Wireless Keyboard from Logitech.

This full-size, low-profile keyboard also includes dual color keycaps that are easily seen using peripheral vision so that you can orient your hands without breaking your concentration. Additionally, the Smart Illumination backlighting turns on when it senses your hands approaching and adjusts to match the lighting conditions of your environment, so you'll always have a clear view of the keys. Customize your keyboard to fit your workflow with the Logi Options+ software for Windows and macOS.

You can also use the software to see your battery level, get notifications if Caps Lock is on, and check which computers are paired with your devices.
