Thanks for posting. I did by the longevity machine and it came a few days ago. So far I'm so happy with it. It's easy to use, and the ozone smells just like the gas my old machine made (it was of a good quality and was very effective). It smells pure and I haven't had any bad reactions like I did over and over with the synergy machine I had. I've done vaginal and rectal insufflation and I've been drinking the water. Wow I wasted like two years trying to get that synergy machine to work for me. I'm really so relieved to have a good quality ozone machine now.
I don't have a concentrator. Do you feel it's worth it? It does seem really expensive. I'll take a look around for the ones you mentioned, but do you have a good seller that you feel is trustworthy?
About the Synergy, I don't like to speak negatively about products because I don't want to negatively impact anyone's business. Yet I feel this is important because it can seriously impact people's health.
I was originally trying to save money by buying the synergy, and I ended up wasting more instead. It irritated, inflamed and swelled anything it touched, and I feel it just wasn't putting out good quality, medical grade ozone. It was impossible to control the intensity of the ozone, despite the fact that it had a control knob. The person I bought it from on ebay did not support the product well. And ultimately I just feel the ozone didn't do what my old machine did for my healht, and I can already feel the difference after using the longevity machine for two days.
I know medical ozone is expensive, but it's worth it when you have a good machine.
