The full-size 105-key keyboard includes 12 convenient multimedia functions, while the ambidextrous three-button mouse is comfortable for either left or right-handed use. Both connect through a single compact 2.4 GHz USB nano receiver with an 8 to 10 metre wireless range, and the required batteries are included to get you started.
