"Impromptu" is a bit of an overstatement. There is "prep-bar," "restroom," and "at home," setups
involved in a number of these tricks. Nothing that's unmanageable. I just find a lot of the tricks
to be less than lackluster. Got a kick out of the fact that a trick didn't work during his
explanation. Not one I'll be relying on.
Here's the major problem for me. The effects
are not for professionals. Pros wouldn't be sitting in a coffee shop and impressing people with
these things. However, the price tag is hefty enough to imply that there's pro money to be made
with these tricks. Not so much. Shelved.
