The HP 655 Wireless Keyboard and Mouse Combo in white (860P8AA) is a full-size desktop set for offices, home offices and reception desks that want a clean, cable-free workspace. The keyboard has a numeric keypad, adjustable legs and more than 20 programmable keys that can be customised with the free HP Accessory Center software, and the ambidextrous three-button mouse has a scroll wheel and a multi-surface sensor (it does not track on glass). Both connect to the PC through a single 2.4 GHz USB-A receiver with a range of about 10 m. Each device runs on two AAA batteries, with HP quoting up to 20 months for the keyboard and 24 months for the mouse. The keyboard measures about 428 x 115 x 18 mm and weighs 430 g; the mouse is 120 x 70 x 41 mm and 90 g. The keyboard contains 62 percent and the mouse 69.8 percent post-consumer recycled plastic, and both can be cleaned with common household wipes. Compatible with Windows 10 and 11. One-year warranty.
