Logitech MK270 WIRELESS KEYBOARD AND MOUSE COMBO

Wireless Connectivity: The set uses a reliable 2.4 GHz wireless connection via a single, tiny USB nano-receiver that you plug in once and forget. The range is typically up to 30 to 33 feet (about 10 meters). 
Keyboard Details:
Layout: It features a full-size layout with low-profile, whisper-quiet, membrane keys, a number pad, and full-size F-keys. 
Hotkeys: The keyboard includes eight hotkeys (also referred to as shortcut or media control keys) for instant access to media controls (play/pause, volume, mute), internet, e-mail, and the calculator. 
Durability: The keyboard has a spill-resistant design with drain holes and durable keys built to withstand millions of keystrokes. It also has sturdy, adjustable tilt legs. 
Mouse Details:
Design: The included mouse is compact, contoured, and ambidextrous, making it comfortable for both left- and right-handed users. 
Precision: It uses an optical sensor for smooth, accurate cursor control on most surfaces. 
Storage: The mouse features a built-in storage compartment for the USB receiver, making it easy to transport. 
Battery Life: Both devices offer extended battery life: the keyboard lasts up to 36 months (using two AAA batteries) and the mouse up to 12 or 18 months (using one AA battery). Both have on/off switches and an auto-sleep mode to conserve power. 
Compatibility: The combo is plug-and-play and compatible with Windows and Chrome operating systems.
