good quality, very bad design

It is indeed a cover that can hold the tablet very badly but the keyboard:
Clipped, forcing, on the keyboard shelf can neither close nor completely open up to more than 90 ° without forcing the clips to avoid damaging or break: the cover is too thick on the tablet should be a hull design to the tablet that does not form thick thereon.
The design of the keyboard cover does not carry all, even un-clipped.
It's very unfortunate because this cover is quality and serves only in the case tablet form.
The dissemination of this tablet with keyboard is so marginal that it I could not find any suitable case?
