The keyboard itself is (as it is written here already often) visually and functionally quite ok, the problem is just the fact that the keyboard is not with my Android Tablet Sony Experia Z2 cooperates. I've been using the keyboard and the Tablet to the university to take notes on PDF files. The keyboard inactivated without saying about every 2 - 4 min, and deletes everything I write, although I bought the proposed app. In addition, the keyboard responds very often simply do not if I want to write something.
Then I wanted to return the keyboard and sat down with the Händer contacted this but has since not been reported to me, which I think is pretty bad, so I forgive even such a bad review.
