The trick is good and the teaching is solid, but I can't get over the price tag for what's included.
You're basically paying $40 for a couple pieces of plastic candy. The materials for everything
included could not have cost more than a dollar or two. This trick would absolutely be 5 stars at
$15-$20, but I hesitate to recommend this at its current price.
Some other things to note
are there are some lighting conditions to consider so you don't flash, and the candy cannot be
inspected without a switch. There are extra pieces of candy included so you can switch them in and
out for the gimmick, but you'll obviously have to ditch and retrieve them during the performance if
you want to start and end clean.
Hopefully this review will help you make a more informed
decision on whether or not this trick is worth the buy.
