Review on Ivation Portable Ozone Generator 600mg/h – Enhance Air Quality & Sterilize Safely with Silicone Tubes, Diffuser Stones & Timer; Multipurpose System Purifies Air, Water, Food, Toothbrush by Savannah King

Don't buy, you lie! I have a 300mg O-Zone generator and this doesn't work as well as they say 600 but the label on the back of the product says 400 and I know it's not half as much as 300, no smell by O Zone. At the exit, some air flows, very weakly, through the air stone. I'm very familiar with these types of devices, my husband turned out to be an O-Zone expert and that's a lie. Also, it's a fully manual control, it's not automated, you have to press a button every time you want to use it.
