I'm in total agreement with ikota and rog. I've been on many forums over the past 10 years and none of them compare to the wealth of good ozone knowledge that is available on this forum. The information is out there for the true seeker. Our responsibility as users of oxygen therapies is first to filter the good from the blatantly bad information, use our own good judgement, and proceed with a full sense of responsibility for our actions and teach others to do the same.
