Yes, I agree with you but I mean many people buy the book because of the Berglass effect.
I understand that's a combination of tricks and misdirection. But people are looking for the clean Lu Chen's method in the trailer!
There is a DVD included in the Berglas's book. In the trailer, he does Lu Chen's version. But if you watch the explanation, this clean method is missing !!!
WTF ????????
Don't waste your money !
