This is my first bad review, but this gimmick is so poorly put together that it goes against you
when you do the effect, even if you do it flawlessly.
When spectators get the linked bands
they normally point out that they look like they were put together. So, even if they don't know how
it works exactly they see something fishy and your whole performance goes from a magical moment to a
guessing game. They are just bad gimmicks.
