I have own one of these keyboard a few year ago and the key start go bad . the price convinced I to order another , even though so many here say negative thing about it . Suffice to say , it show up , I plug it in , almost half of the key do not work , right out of the box . send it back , lesson learn and order a Logitech Illuminated keyboard . Buyer beware on this Microsoft keyboard , they must have spill coffee on the circuit board plan .
