Total Control

I make it a rule not to buy tricks unless the demo shows the whole performance. (So, I won't order "Clear Choice" despite the good reviews.) The video of "Total Control" seemed to show the whole performance, but the presentation was sort of weird--close your eyes and I'll show this to your friend. I'm not sure why I bought it to begin with. I don't understand the favorable reviews. The entire trick seems to depend on convincing the subject that s/he is hallucinating. How many people are going to buy that?
