This keyboard works perfectly with Dell Venue 8 Pro (under Windows 8.1). Pairing is no problem (Fn + Sign on the keyboard, which illuminates the keyboard and puts the bluetooth research). To turn it off just cut the BT V8P (no on / off switch on the keyboard). To use the keyboard off after 3 seconds you have to press the button "ps" of the keyboard, which turn on and automatically connect it to the V8P (do not attempt a reconnection with Fn + sign, it clears the connection code keyboard and V8P will not detect it). The keyboard itself is pleasant to the touch and robust. The keys are spaced apart and of good size. The trackpoint is very accurate with a detection finger pressure that can move the mouse cursor more or less rapidly. It is powered by 2 AA batteries (included). All good :)
