My Experience:
This trick is an all out miracle. You will get great reactions. The gimmick is very common among magicians and once you know the secret you can cards other than the jokers. It does require some sleight of hand but nothing to difficult. Magic is supposed to be fun so come up with your own story and keep the spectators involved.
Pros: Great ending, Easy to do, Plays big packs small, Gimmick can stay in your deck at all times.
Cons: The results you get depend on your presentation. If you just open it up and only give it five minutes of practice then i would only expect that you will get bad reactions. All in all this is not a con of the effect but of the person who doesn't practice.
With a good patter this trick kills. One of the best sandwich of all time.
