I agree. Those are very cool. Like you said, most of them are easy to pick up on if you have any experience as a magician, but the subtle nuances in the performance made them look good. I just wish demo videos didn't play that obnoxious music in the background. I'd love to see a demo that showed the whole routine and then offered to teach it. I find it frustrating that we are expected to buy something without even knowing what exactly the routine is.
As a magician you should be creating your own routines.
I dont think you need to know the routine that comes with it, in order to buy it.
I rarely use the routine provided, if one is.
