This trick is a great effect if the situation and audience is right. For the price, the props are wonderful with the exception of one glaring problem that could have easily been fixed with two pieces of felt. When "the magic happens" and your individual links are suddenly a complete chain, there is so much noise that it can't be ignored. Some simple felt along the bottom of the cup would have completely eliminated this, but the cup is so small and welded together to the point that you cannot make adjustments to it in any way. If you play with the cup just right, you can make it work with minimal noise--but it will still be there.

Again, for the price, this is a great little trick, but I would have gladly paid another ten dollars for them to have made the one slight adjustment that would make this perfect.
