I was excited to get this effect, but bitterly disappointed after working with it. They only supply
about 5 elastics as replacements. For the price, they should probably include a whole spool of it.
Replacing the elastics was easy, but adjusting it so that a "flick" changes the card is almost
impossible to achieve. Either it's too loose and the card changes very slowly, giving away the
method, or too tight and a solid flick will not change the card. I'm still trying to hit that exact
sweet spot where it will change as quickly as I see in the trailers. I have not been successful.
This was one of my poorer choices of a magic effect. I would advise everyone to pass on this effect
and save their money for another effect.
