Logitech Wireless Combo MK220. The compact keyboard-and-mouse combo with all the right keys. The keyboard is about 36% smaller than standard keyboards but still has all the standard keys. You get a reliable wireless connection up to 10 meters (33 feet) away, with virtually no delays or dropouts-even in the busiest wireless environments. Wireless range may vary due to environmental and computing conditions.
