Welcome to our forum.
I remember seeing a commercial as well, I think it was on CNBC.I didn't pay much attention to it but I remember thinking about them going mainstream with their commercials. And apparently thay have done something fantastic to become more energy efficient.
Same with me! It was their commercials that sold me on getting a spa. Then went to this forum and another and found out the "real deal", and ended up shopping around. I'm glad I did!!!
