The ASUS W5000 is a wireless keyboard and mouse combination designed to enable comfortable work on a PC or laptop without annoying cables. The extremely flat 11 mm keyboard features chiclet keys and durable, high-quality rubber dome switches for quiet, responsive keystrokes. The W5000 keyboard is energy-efficient and operates on the 2.4 GHz frequency band for a range of up to 10 meters. The mouse automatically enters power-saving mode when not in use. In the center of the mouse, there is a small LED indicator that lights up red when the battery needs to be replaced. When you're done, you can securely store the USB receiver in a small rectangular compartment on the underside of the mouse.
