To be honest I bought this hoping for a gimmick that would help me cheat on the sleight normally
required for these tricks, and it does. One downside is the folded card or bill, but then again I
don't think you can do the sleight with coins. It's still a little hard with fingers that aren't
flexible, but at least it's possible with the gimmick. I'd like to see a lower price or a little
better quality.
As a follow-up I would give this a 3 because in practice you'll also have to supply another material and do set up that could be annoying, especially if you switch between cards and coins. And yes, you apparently can use coins with the right material that you'll see in the private discussions.
