I have both these DVDs and they are pretty good.
Nestor Hato's DVD focuses fully on the Nestorizer, so if youre wondering about other things, then too bad.
Yannick's is about close up magic.
The Nestorizer isnt all that amazing. Most magicians will be able to figure it out with some thinking. I acutally came up with the exact same gimmick about 2 years ago. But i couldnt perfect it so i never bothered to show anyone. His gimmick is exactly the same as mine but he uses better materials to build the gimmick haha. basically its able to be a hands off under the bowl haunted pack
I'd say yes, the gimmick is easilly reconstructed in a magicians head, but that means nothing to a working magician. I work to entertain and amaze laypeople, not magicians, and the Nestorizer is a very cool, and very versatile little gimmick. It's versatility takes it far beyond being just a tool fpr a haunted deck. I use mine, when combined with sleight of hand, for some of the smoothest switches, and most visual colour changes going. I love it!
Plus, there are a couple of things on the DVD that don't use the nestorizer anyway.
I can't wait to grab Yannick's DVD
