This is a good product. The trick is a historic classic. It is easy to do and not something people will really figure out. Although they always try and guess. So you'll need to make your performance like magic to avoid making it like a puzzel. It is also best suited for parlor or something cool to keep at home. But that is kind of expensive to just keeps at home to entertain. The location of where it is performed is some what limited, but not too much of a problem. Overall it is recommended.
