I have just been contacted by a manufacturer who had seen these on Ebay and purchased one for evaluation.I'm afraid it is not pretty reading.The just of it is that it does not produce the amount of Ozone advertised. The one they received had no earthing to the case making it dangerous.The ceramic plates inside are Chinese and can give off Nitrous Oxide as a by product.They have reported this to trading standards as they believe them to be dangerous and do not comply with CE certification.Anyone who has purchased one let me know and I'll put you in touch and send you his findings.
Everyday this forum slips further from God.
