This is a great wireless keyboard, except for NumLock. Good feel, long range, touch pad works well. Unfortunately, the keyboard includes the laptop computer num lock option, where certain letter keys become number keys. More unfortunately, the label on the num lock key is invisible, as are the letter key alternative number labels. So there's no indication whether num lock is on or off. These invisible labels look like they should light up, which would be most helpful, but they do not. I think whomever thought up laptop keyboard numlock was dazed, confused, or maybe ill and wish there was some way to disable number lock on this keyboard.Adesso 2.4 GHZ WIRELESS SLIMTOUCH TOUCHPAD MINI KEYBOARD SILVER W/BLACK KEYS ( WKB-4000US )
