Minor points:
- Rarely it happens that a key "stuck". I can not at the keyboard visually still see mechanical sense, but sometimes (as I said, rarely) a character writes becoming increasingly interrelated, and I have to push again to stop) the. Whether this has to do with my sometimes improper transport in the backpack without cover? May be.
- The cover has 2 small drawbacks:
1) There is no possibility, the keyboard is to "lock". I mean, you can slide into the keypad, and when they do these things in the air, the keyboard could be equal to slip out from the other end again. Suggestion: Remove the cover at one end (semi) closed to run ... and perhaps "Einschiebende" also come up with a lock. The closed end would be much better, even without locking up, because in most cases represents the whole is perpendicular to the backpack so that the "open" end up and nothing can happen during re rausnehmen.
2) When (slightly thinner) iPad Air, there are some "air" between the retaining rail and the iPad, so the iPad something too hard wobbles when you print on the display for my taste. Maybe I glue a thin padding strips there to minimize the (just strikes me as an idea). But the design is acceptable anyway. One must not work with a lot of pressure only. And by the way: The Tastatatur provides useful shortcuts that make some finger pressure unnecessary.
Overall, I am of the keyboard, which is the almost constant companion, loved it! So the disks on iPad makes a real joy. No comparison with the knitted Ockele on the onscreen keyboard!
So just buy it for anyone who can really write want and do not want serious solution.
Addendum 08.07.2015:
The keyboard I still love her. 2 of 4 glued anti-slip feet are now departed, making the keyboard easy "rocker" when writing. But you can get replacement feet from the hardware store (then every 4 exchange).
