Alex Smith AKA Jonathan Royle is a joke, and possibly a fraud. The last time I bought something from this clown he attempted to sell me a bunch of pirated PDFs. I know they were pirated because the books have yet to be released as PDFs almost 20 years later. If you read reviews of his stuff you will discover that he should be paying YOU to read his BS because he is as horrible a teacher as he is a magician. He rarely includes a full routine, you just have to watch him awkwardly perform something and then guess that it's what he's trying to show you but even then it's incomplete and he'll tell you "well, you need to know how to do this move that I haven't included"(more than likely because he couldn't get permission from the original author.

Avoid at all cost.
