The video is about 16 minutes long and, and the teaching is good, easy to understand. This trick is
not very sleight-y, and is appropriate for beginners. There's a little setup needed before the show
gets started.
Downside? I'm not sure I will perform this, and if I do, under fairly
specific circumstances — for an anniversary couple, or newlyweds, and so on. Have two strangers as
spectators? It might be a bit awkward, but it could also be very funny, depending on your
presentation and the audience. So, if you like the plot, it's a solid routine, but you may need to
search for the right opportunities.
One variable that seems very tricky to me: watch the
trailer, and the two participants follow instructions and have their sandwiched effect revealed at
just about the same time. This is the ideal outcome, but I can't imagine it works that way very
often. One spectator is bound to reveal the torn out heart first, or the other way around. This may
or may not be an issue for you, but you'd want to consider how you manage it. The video doesn't
offer any suggestions to encourage a simultaneous reveal, or what to say if the spectators don't
have a coordinated reveal. I'm sure I'm being nitpicky, but consider this for yourself.
All
in all, a solid effect with limited (to me, anyway) applications. Where it can be applied, it looks
like it works great.
