The keyboard pleased by reliable connection recording, in this case with an HP Slate 21 AIO (All-in-One-PC). Another plus is the very good typing feel. It provides a medium long stroke with fixed and definable stop. Slightly confusing was the integration into the Android operating system. Since it has a Windows key it seems likely, that is that their true destiny. After some trial and error, however, found in the Android system control (Language & input) the corresponding menu items (More keyboards). After that everything went as it should be. As a single negative point I emfinde only the lack of a hardware on / off switch to conserve battery life (2 x AAA).
