Now the keyboard itself:
The manual has exactly to the point, how to make the Bluetooth connection to the tablet. The connection is very good problem-free use of the keyboard is guaranteed as long as the keyboard is charged. In the long-term test, the battery life is very long in normal use the keyboard, lasts substantially longer than by the tablet itself.
The Case-properties of the product I am also very pleased. The tablet can be properly hang the case and serves as a screen protector. Due to the soft surface of the areas that come into contact with the tablet, there is also no risk that the keys might scratch the tablet screen.
For a portable keyboard, the keys are a good size and offer a pleasant writing sensation. Particularly positive, I find that you, thanks to the Bluetooth connection, any other Bluetooth-enabled device can connect eg your smartphone.
