I have gotten great reactions even with just a minimal presentation effort. At work, Hey wanna see something weird... perform. People cringe, and when you think about it there are more selections than just three, however they might be harder to apply the blister. The only limitation is that you have to have a lighter.
Its great; something that you can carry with you always. The only problem I could foresee anyone having is that since it is such a visual effect, people will want to see it again. Its not too much of a problem though, because a real simple out is to just say "No, do you know how much that stings/hurts, Maybe later" Or one could just under-react and just burn yourself and nonchalantly reveal the blister, that could mess up the performance.
The gimmick should last a lifetime, unless you lose it or somehow purposely try to break it. And you do get two gimmicks, one for a mini bic lighter. What is really great about it is that it can be performed with minimal sleight of hand and if handled properly can build your "magical confidence" as noone would suspect that type of gimmick, even though it is in front of them. They also never think of a force or suspect that you did some typical card sleight.
If you can afford it I would get it. This is my first card blister effect, so i dont know how the others compare, but I do remember some diatribe about the development of branded, and it does mention that others had pointy edges among other things whereas the edges of the blister in branded are rounded to look realistic
