I have gone to his class. Ive know him for years. He was a counter guy when I was just a kid starting out. He was crazy then and he is crazy now. Nice hair piece too. He goes on planes, bars and hotels with a portable CO detector! Not saying the diverter is wrong. Just getting all the agencies to understand that it DOES work and having local inspectors recognize that is next to impossible. They look at em, ask what the hell "that" is and turn em down. Nothing like being "outside of the box". Bubba
