What you see in the trailer is not what you get. I really like Hanson and he has a lot to offer but
in my opinion this trick wasn't one of them. Even during the training, the rubber band did not come
all the way around most of the time and ended up in front of his knuckles. The three position change
is barely doable. The four position change is completely ridiculous and is not what is shown in the
trailer.
I don't really agree with you, I just got the trick and really like it. I think what you see in the trailer is exactly what you get. BJ4 is actually a revolution, that is quite hard at the first time, but believe me, this worth its weight in gold. I'm happy with my purchase, highly recommended for every rubber band's lover.
