It's not as reliable as one would hope for. Because of how it fits on coat if you're the type of
magician who moves around a lot, the hold out has a tendency to swing out of place and folded cards
will occasionally drop out of the device because of this. It's easily solvable by using a safety pin
and putting some double stick tape here or there to help the cards grip more, but I wish it had two
magnetic hook ups instead of just one, and that it held the cards in place. It does what it says it
will do though, so in the end it works.
