I, personally, found the act a little tough to watch. To be fair, it wasn't Cody; More of a tough
audience.
With that aside, the effects didn't appeal to me as much as I hoped.
As
Dan said, Killer Prediction is probably worth the price of admission.
The Bill in Lemon
requires a product which is pretty pricey and there's other products you may have to buy directly
from Cody.
I would add one correction:
To do Bill to Lemon exactly the way Cody does it, there could be the need to buy the gimmick.
However, he does make it clear that it is not required, as you state.
Small point, but since he does mention that in the lecture that it isn’t required, I thought it necessary to clarify.
