This is definitely a usable idea. I gave it 4 stars instead of 5 because I thought the price was a
little high for what you got- just my opinion. The gimmick seems decent but the teaching part is not
particularly elaborate- about 19 mins for two variations (including the trailer footage). Somehow, I
was expecting more ideas but it's just really the two tricks you see on the demo. The tricks
themselves are pretty bare bones and an experienced performer can probably improve upon the
presentation/ misdirection he offers but it's good enough as it is to impress your average
spectators.
