Hi didge333
I have no experience with their products but having looked at their ozonators I will comment that they look well-made and are very well specified and documented. The site reminds me of the kind of quality documentation you get from Ozone Services. The website certainly has the right information. I will comment that their concentrator, in the opinion of a friend of mine who deals exclusively with concentrators that the Integra is not all it's cracked up to be and extremely overpriced. I don't know. I'm just passing that on. I do think the features on the ozonator make it a fair price as long as their calibrations are accurate. It is not a dual-dialectric unit which is a drawback for bloodwork uses.
my 2 cents. Take it or leave it. best of luck!
cheers,
paul
