I used this for the first time when I was 17 (I'm 65 now), and eventhough the trick is very easy to perform (even for an old codger like me) it really packs a wallop for a finish. For an inexpenive trick, with the right showmanship it can make your audiences eyes pop and their jaws drop. If you want something that does not cost a lot and has a strong finish, I would recommend the Siberian Chain Escape made by Royal Magic. The chain is well made. I had a problem with the lock, but I notified Penguin about it, and they didn't waste any time sending a replacement for the trick, which worked like a charm.

for $5 you get a quality chain, lock+key, and instructions/secret. high value trick that can impact hard for little money and little difficulty. a great way to satisfy some expectations on a small scale.
