This is one of those tricks where getting caught completely depends on you. How you present it and how confident you are with it. The trick is overall easy to do with practice, but the hard part is getting it through as a magical effect. (For example, do you find yourself getting caught palming cards, or ditching items into your pockets, if so you might want to reconsider getting the trick and think more about working on your confidence and misdirection). I have it, and I love it. But I am careful with it. Also note that Michael Ammar stunned the world using this trick on the Tonight Show.
