You've been typing on a keyboard that splashes coffee across your keys and clicks loud enough to wake the office. The MK540 combo is built for people who need it to just work. Spill-resistant design, whisper-quiet keystrokes, three tilt positions so you can find the angle that saves your wrists. The M310 mouse has soft rubber grips and a contoured shape that sits naturally in your palm. Batteries are pre-installed – keyboard runs 36 months, mouse 18. Plug the Unifying receiver in, you're productive before your coffee's cold. Windows 7/8/10 and Chrome OS compatible
