While the switch is flawless, I wonder whether the need to carry a specially prepared item that is
good for only one performance and then requires reset is ultimately practical.
As well,
somehow I wonder if the change of the folded card to a bill - which is quickly taken from the
participant's hand to display (a process that implies defensive guilt) is worth all the effort.
Indeed, the necessity to set up the wallet to receive the card is not at all convenient or clean
and, once again, must be carefully reset for the next performance. Not practical for a table-hoppng
environment.
In short, this item comes across as something designed as nifty to demo and to
sell but impractical for a working performer. Bad angles, troublesome setup, and awkward pen
'moves' do not impress me much.
