Designed for Comfort, Tuned for Productivity

The MK850 Performance bundle prioritizes ergonomics and workflow efficiency. The keyboard's cushioned palm rest and curved keyframe promote a natural wrist posture while three tilt positions (flat, 4°, 8°) let you optimize alignment. Concave keys with a large strike area improve accuracy while reducing noise. The ergonomic right-hand mouse complements the keyboard with a soft-rubber finish, eight programmable buttons and a Hyper-fast scroll wheel that accelerates navigation through long documents and web pages.
