its a bit pricy, but its definitely a great trick, comes with tons of paper and doesn't require a lot of practice to get started. The pad is only the first part of the trick however, you must sell the routine by acting like you can really see into their minds, rather than just looking at the peak and blurting out the thing they wrote.
I'd give t 4/5 but only cause i feel its a bit overpriced. other than that its awesome, high quality tutorial and high quality paper.
