All dvds try to have selling points. The ones for this one are very good. This is the most detailed work on card under drink to date. The rest of the work is scattered, or very limited in the work of jc Wagner, Gregory Wilson, other bar magicians and the like. He gives a half hour act with the running joke/miracle of card under drink. Its tested and very solid and allows you to create/fit it into your routines.
Maybe card under drink is not your style, I can respect that, but to trash it and not recommend it based on YOUR personal preferences alone rather than giving comments to the actual content is quite a weak opinion (and I'm being nice)
This DVD is what Doc considers his most important work, and one could only wonder why...
