This will be very brief. The gimmick is built very well and I appreciate that they overdubbed the
video in English so you're not stuck reading subtitles. It's a fun gimmick for sure but it is much
too loud to use in a quiet setting. It would be best for table workers in a loud restaurant or bar.
I think that if done in front of a fairly bright spectator they'll be able to figure out how it is
done just by the loudness.
