For a one-on-one effect, this is okay. You have angle issues that prevent this from working on too
large of a crowd. Also, the description says it includes a ring you can hand out for examination.
That is true...except for the fact that the examinable ring is noticeably different from the one you
do the effect with. The effect ring has a constant shine over it, while the examinable one has a
very dull design in the middle that doesn't shine at all and won't. This isn't a subtle difference
here at all; even a casual glance will tell the spectator you aren't giving them the same ring. That
means you have an effect where you "show" a black ring and change it to silver (or vice versa), and
then you have to pocket the ring afterward and move on. Yes, crowd control can manage that, but the
description says you can hand something out and that's misleading.
