This is one of the most amazing gimmicks I have ever bought. I would not recommend this to 21th
century people that can't do math in their head very well (I was worried at first but I picked it up
quickly) and there is so much you can get out of this, the best $75 I've spent in a long time--greg
never fails to produce top-of-the-line magic. I was performing this within a couple of hours and it
is so diabolically deceptive, but you have to build up the performance and stress that your pocket
is empty except for the amount of change the spectator freely names. Highly Recommended.
