I'm really sorry but I don't like this trick at all.
I got it as an extra from "In the
beginning there were coins" DVD and I am very happy I never paid money for this silly trick. First
of all it is very overpriced, and second of all, I have never used this trick.
I've had the
trick for many years now, and I'm having trouble thinking of a time to use this coin flip. Even if I
do, it does not really look like a fair coin flip...
It's pretty expensive for what you
get, but who knows, maybe there is someone who will find it very useful.
