RTFM does not support Bluetooth. But it does exactly what it should. You can put it in and out of a carrying case, take notes, use it as a pen, and it has a rather small point of contact with the screen. The only reason it doesn't have 5 stars is because they don't have a spring behind the button (because it doesn't support bluetooth) to play around with, so it's not that fun to play with.
