Also I had ordered the Wallet STRUCTURE. This is just as useless for me. The flap is mounted such that it interferes with the holding of the iPhone and the mounting shell (so that the folding stand-up effect is achieved) fixed at only two points. This makes the use of the iPhone to a juggling act. On the one hand you have to be careful that a non-folds away the iPhone, on the other hand you have to constantly buckling the strap disturbing .... No, that's too annoying.
I've returned both cases by return mail.
