Ok, I found them on the Web. They're at
Home
I'm surprised they make no mention of this in their invitation. Maybe they don't want anyone to have an idea of what to expect. If that's the case, the red flags are popping up already.
In any case, they have two products they sell (of course, it's a sales pitch). One is a thermal blanket cover to place over your attic insulation. Their claim is that it does not induce mold or in any way traps moisture, and it "breathes" a very little to prevent this. Their credentials seem to prove that - you don't typically get a UL seal without doing what you claim.
I found a site on the Web where this product was pitched elsewhere, and the cost to install was exorbitant, and the reviewer was able to find a local contractor who could do it for a third of the asking price.
So I'm skeptical. If you're going to rake in a few thou, a free meal is nothing.
The other product, I really don't know what it does. It attaches to your electrical cable into your home and does something where it smooths out the delivery of amps, minimizing spikes with something called the Power Factor. I've seen nothing elsewhere on the web about how well it works.
The insulating product, elsewhere on the Web reviewers have said that it does actually *work*. It's the return on investment that I question.
And I'm always skeptical of anyone who can't just tell me up front what they plan to show me. Smells like BS to me.
