Enjoy smooth, precise, and comfortable typing experiences with the MX Mechanical Wireless Keyboard from Logitech. Its smooth matte keys feature tactile quiet switches that are designed with a tactile bump, providing you feedback as each keystroke is registered while minimizing noise. 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.
