The MX Keys from Logitech is a keyboard designed for stability and precision. Increased key stability reduces typing noise and optimizes responsiveness. Proximity sensors detect hands and activate the keyboard backlight as your fingers approach. The intensity of the illumination automatically adjusts to the lighting conditions, but can also be manually regulated. When the user leaves the desk, the illumination of the keys turns off. When fully charged, the power lasts up to 10 days or up to 5 months when the illumination is turned off. Charging is done via the included USB-C cable.
