Clever trick, but very poorly constructed. Things don't align, quite as well as they should, and one
particular component of the apparatus is easily subject to a fatal flaw...which, if you know what to
look for, even occurs in the explanation video. If this were produced again, in sturdier materials,
and with closer attention to detail, I'd gladly pick one up. In it's current state, I would
discourage anyone from purchasing...even as a hobbyist, mine very quickly ended up in the garbage.
