The main problem with this keyboard is that when you're typing, one out of every ten or so letters will not register, so you are constantly having to press backspace to correct yourself. The touchpad is not much better, and results in jerky mouse movement on the screen because it is constantly trying to keep up with your movements.
I figured this unit would work and feel like the bottom part of a laptop, but this is not the case at all. Very annoyingly, when you first turn on the computer, the num lock is on (which is a computer setting, not a fault with this product) which means that half the letters on the keyboard are taken over by the virtual numpad, but to turn this off, you have to hold down one key and press another. Because the keyboard performs so poorly, it's hard to actually tell if your key combination has registered, and there are no indicator lights for num lock or caps lock (understandably, to save battery power), but this means you end up repeatedly attempting to turn off num lock so you can actually type, only finding your attempts have been futile because the keyboard seems unable to register two simultaneous keypresses.
