I know Troy Hoosier and have seen this gaff devistate a room of magicians.
By devistate I mean that you cannot achieve this effect the same way by Sleeving.
Combining this gimmick with Sleight of hand really creates a unique feeling of magic.
I like Triple Threat better than the 3CM gimmick.
Imagine doing 3fry with your sleeves rolled up ....you vanish the first coin and show both hands empty, Vanish the second coin and show both hands empty then flip the last coin in the air, vanish it showing both hands empty.
Then make them reappear one by one from your hands or some impossible location. Davastating.
There are a number of good routines in the book that come with the gaff.
The magnetic aspect of it is what your really paying for along with the two [ coins. Quality is always worht the price if your going to use it in a professional capacity.
