Pull Klebrückstände on the keyboard of film, but keyboard works fine ..

As Steve has mentioned it, are Klebrückstände, peel off the film leave.
It bothers me very well, but funktionier the keyboard properly and let himself equal with my iPad 2 connect.
The keys are also good (similar to a notebook) and I really like it! (Apart from the klebrückständen)

I had the the residue with nail polish remover further attempts to clean it and it worked (although laboriously but it's now clean)

Whether the keyboard you should buy or not?

It depends on:
- Does you the Klebrückstände? (Is actually the only thing that bothers me at the keyboard)
- If you are a lot of writing on the iPad, then they fold up keyboard is very cool and very convenient :)

Overall, I'm on ... 4

I hope my review has helped you a little :)
