I really like the concept in general, and the tutorial gives you plenty of ideas to get started in
using it. I'm sure that these are generally well made and I just got a not so perfect one (see 2&3
below). I think this product could be improved upon, nonetheless it is fun to play around with.
Downsides:
1) You have to be careful not to flash the edges of the deck. The gimmick is
highly reflective and does not in any way look like the edges of cards (even brand new ones). I may
attempt to dull the sides by coating it in white out, or some kind of white paint with a dull matte
finish. Also, because there a holes for the smoke to escape, you have to be extra careful to cover
these.
2) It makes a crackling noise when it begins heating. If you aren't careful to cover
this up somehow, it is easily noticed.
3) Unfortunately, my gimmick does not close
entirely, leaving a portion of the back end lifted. This causes a tight seal to not be made and the
smoke fills the inside rather than being forced out the slits. Less smoke escapes = less fun.
