Since I use my tab on the work and it is very difficult on the Tab (touchscreen) screaming with the internal keyboard, had to be an external keyboard. That this same time provides a protective covering for my Tab is better. ;-)
What is also very good, is the compatibility. Simply attach the keyboard, activate Bluetooth on the tab and the keyboard and away you go. The default setting of the keyboard was English with me. (Z and Y were thus vertausch. Also ü, ö and ä did not go). To point "control" you can then select Germany. Then everything fits and you can get started.
In general, the operation of the keyboard is very well possible. You quickly get used to the small keyboard. (Compared to the full-size keyboard)
The Cover function is also very good and protects the device reliably.
If you fold the keyboard so is a further advantage that the keys do not rest on the screen. Have the thus unscratched an anti-reflection film. (The problem I had with my Tab 10.1)
What is good also, all ports (incl. The camera) are not covered by the protective covering. Thus, no restriction in the use of shell
A small drawback is that you can not adjust the tilt angles from the keyboard tab. there is only one position in which engages the part. For me is a bit annoying when you're on a long train ride. Since it would be great if you could change a bit the angle.
Otherwise I am so far very pleased with everything.
The battery life of the keyboard is indicated by 3 months (with normal use). Whether that is true, I can not say right now. Will it but announce here as soon as I can tell.
Conclusion:
A very successful Tab case. You get a good quality for a fair price. (Quality costs just)
For a good keyboard with a protective case to pay about 100 is fine.
I am satisfied and can recommend this part.
