Buyer BEWARE! While the keyboard & mouse work well for simple word processing tasks, there is a known flaw in the keyboard when playing games! Basically, in games where you have to hold down a button for a long time (e.g. an FPS game where you hold 'W' to go forwards) the button will stop working when simultaneously pressed with another key (e.g 'A' or 'D' to strafe in an FPS game) thereby rendering the keyboard useless for everything but office tasks. This flaw affects more Microsoft keyboards than this one so do some research on the net before you purchase. There is currently no solution available to fix this!
