Thermibreast - is it effective? Seems like it's been around, has great reviews, but it's hard to find a provider.

Despite having been out for a while, ThermiBreast doesn't have a lot of information online or providers local to me. It makes me hesitant, because getting a couple inches lift without surgery seems like a great concept. I've found some places within 5 hours drive that do it, but no before and afters on their websites etc. What's the deal with ThermiBreast? With all the positive reviews, why don't more do it? How do I choose the right provider? Thanks in advance!
