Logitech MK235 keyboard and mouse combo, wireless, grey, QWERTY-US, 920-007931

Sturdy build with angled feet and a spill-resistant design. Tear-resistant treatment on every key, so you never have to worry about letters wearing off your keys. No learning curve involved. You will enjoy the comfort and simplicity of a traditional full-size keyboard layout from day one. Type for up to three years between battery changes and use your mouse for up to one year before replacing its battery. The three-year battery life estimate is based on approximately two million keystrokes per year in an office environment. As with all batteries, your experience may vary depending on usage conditions and computer system. Simply plug in the small USB receiver and enjoy a strong, lag-free connection. Your wireless keyboard and mouse work up to 10 metres away. Environmental conditions may slightly change the range, but you will always have the connection you need.
