I was waiting for a review on this myself, so I would like to post one if anyone else is waiting.
This is really cool, I'v tried this a couple of times, and when I get it right the
reactions are better than I am used to. The cool thing about this is that the spectator really feels
that everything happened in their head, and it really does! They never say anything.
However, the video is a bit misleading if you ask me. It's not really how it looks like, though
that is how it feels for the spectator. I'm very happy with the effect and the method.
Now, two times when I have performed this, it didn't work. I have been doing magic for 10 years,
and I know that I have to practice to get it right every time, but it is possible for it to go wrong
if you don't give clear instructions. To me, this is a minor problem, and i look forward to lerning
how to get it right every time.
This is really fun to perform, and mindblowing if you get
it right. I would recommend it if you are serious about it, and if you are willing to pay 50 bucks,
I assume that you are!
