The concept of this trick is what attracted me, together with the price. And both of those are accurate. However, the teaching skill manifested on the video is, in the opinion of this professional teacher, quite poor. Three easy examples: (1) some commercially available IDs make the suit pairings different from this author's method. Pointing this out, early on, would have saved a lot of time and frustration. (2) A very helpful picture of what should be written on the ID cards appears over 9.5 minutes into the video. Putting that sooner, or stating it was coming, would spare the viewer from trying to follow this teachers fast speech in understanding how to complete the task. Third, at no point is there a list, PDF file or picture of what the non ID deck looks like when properly constructed.

A teacher who proceeds MUCH SLOWER and assumes that his audience is 100% naive to the approach, would go over much better. Yes, some experienced magicians will likely disagree, just like the stronger students get As even when the teacher isn't very clear...I'm too frustrated to continue now and will need to come back to it later, if ever.
