The Wireless Keyboard K350 from Logitech is a wireless keyboard for use with Windows-based computers. It uses the included Logitech Unifying receiver, which plugs into an available USB port, to communicate with your computer sans wires. This receiver can also be used with other compatible Logitech wireless input devices, eliminating the need to use a separate receiver or keyboard and mouse.
The keyboard uses high-frequency 2.4GHz technology, which eliminates dropouts, delays, and interference. It is built with a contoured wave design, which is designed to compensate for the varied length of your fingers. A contoured palm rest provides extra typing comfort. Multimedia controls and programmable F-keys let you better control your computer. The keyboard can operate for up to 3 years between battery changes.
