I bought it and it works just fine. Things can get crowded on an iPad mini, but that's not your fault! Very useful. I wish we had a choice of camera icons - I happen to have a digital Hassy, but use a DSLR a lot more! Oh, and it would be nice if the posing cube could be scalable. At the moment, it is easily confused with a person or object placed on it.
Oh yes, I haven't yet worked out what the third button on the left at the top is used for - the one that looks like a paragraph with an eye.
