The Logitech® Wireless Combo MK520 puts convenience and control comfortably at your fingertips—whether you use a laptop or desktop. The full-size keyboard gives you the room you need to type comfortably, while the concave Logitech Incurve keys™ cradle your fingertips. The full-size mouse offers smooth, precise tracking and feels good in either hand—hour after hour—thanks to its hand-friendly, contoured design with soft rubber side grips. And your desktop is hassle-free with up to three years of battery life for the keyboard and 18 months for the mouse,* a tiny Logitech Unifying receiver that you can plug and forget, and Logitech Advanced 2.4 GHz wireless connectivity.
* Keyboard battery life calculation based on an estimated two million keystrokes/year in an office environment. User experience may vary. Mouse battery life may vary based on user and computing conditions.
