Getting Connected:
The hardware is compatible with many devices. I have a Xiaocai X9 (phone) itself so that it is compatible.
Joining is easy via Bluetooth. Bluetooth on, enable keyboard, looking at the device to other devices (including the keyboard) and enter a 5-digit number sequence.
The layout:
What is somewhat problematic, the German layout does have all the letters and numbers as where they should be, with the characters but you have to try to start something and try different. Keyboard Shortcuts.
The "\" I have not yet found, and the arrows were not found by me.
Stability:
The keyboard is me on many occasions dropped (even with my tablet in it) is something attacked (the frame holds no longer quite so good side of the space bar), but it still works and I find that quite well.
For once it has the tablet also protected (so my impression). Because if the combination of keyboard and tablet hits the ground, the energy of the fall will be distributed to the "splintering" in tablet and keyboard.
As was the case with the Ancients phones. Are the fallen down, they are shattered in all items, assemble and working again. Nowadays, the display is zerplittert. (I matter digress)
If I had not had the keypad turn on Tablet would probably also my display fragmented, so you do not.
To use:
it taps her quite well. I use them for the lectures at the university and am quite satisfied.
At the beginning you have to get used to, that there is a small area and the nipples at the space bar (so that the tablet "is held close" in) is in the way.
For truly great men's hands, I would advise to try and possibly return again. With delicate hands, as I have, works quite well.
