Like Steinitz I use the AroMed. I've been vaporizing for about a year but as my chest is sensitive i've found vaporizing still irritated my chest. Since using the AroMed my chest has felt better than it has for years, very happy with it! I think the problem with most is they're vaporizing too hot so toxins are still being inhaled. I never go above 195C/383F so stay below the point such toxins are released into the vapor.
