after some difficulties in the Keys - Top!

The keyboard has a great look, fits very well with the tablet, looks very solid, etc .... But first I wanted to already return, as some keys were not staffed properly: YZ were reversed, the umlauts did not work (ä, ü , ö), and some punctuation - I was totally disappointed as a much cheaper no-name keyboard worked flawlessly. Using the app External Keyboard Helper I have tried for hours without success. Then I let it go ... and then: as if by magic, suddenly everything works fine - this text I wrote with the keyboard and would like to encourage everyone not to throw in the towel the same - sometimes it takes a Update or similar ... because the keyboard is also a good protection for your tablet, yet not too hard ... So: Full marks
