This is my first review. It didn’t take but a moment to like the trick. It’s a good trick. It could
be one of those fail proof gems. However, like I’ve seen in another review, the watch that you
supply may be difficult to find. While there are many on the market and they are pretty accessible,
it seems that the modern watches don’t seem to be “exact” in the function it’s supposed to perform
(two click). I’ve tried many at a couple of different retail stores. They do function properly but
are easy to miss because they don’t seem to be made like they used to be. If someone could link to
watches that are more fail-proof, I would change my review to a five star.
