On iOS, the keyboard works fine and is easy to couple. In Windows, it can be depending on the Bluetooth software that the coupling has to be repeated. So if it's not immediately restart, cancel pairing, erneutkoppeln. Then there solltes funktioniern. Theoretically also simple. However, I had problems with my rooted tablet. As far as I could find out with the help of really excellent support it now, it involves a software bug on the tablet, and not at the keyboard.
Typing can me her well and quickly! From a distance it looks good too. Come to her but to close one recognizes the 40-60 price difference for Apple keyboard yet. The price for the look is appropriate.
My conclusion. Good, functional and an unbeatable price!
