A little less than 5 months later, it malfunctions
No, I don't have an image to show you of this malfunction. Within the last few days of this review, I noticed the green light didn't blink when I opened the fridge. I assumed the batteries were drained, so I replaced them. Still no green light. Not even a red light, but I noticed the O3 pouring out, so I stuck it in the fridge. A few hours later when I opened the fridge, I noticed the fridge air was completely saturated with O3 - highly unusual behavior for this product. I have to assume that, since the LED light no longer works while there is a constant stream of O3 instead of the "puffs" it should be providing means this item is malfunctioning.<br /><br />Here's the thing: You know how the Amazon Server, sometimes the seller, is in a rush to have us review things? Well, my return window was only a month from buying this product. Then Amazon gave me the run around on product support only to repeat to me that my return window closed in July. I would have given 2 or 3 stars if not for this.<br /><br />I treated this thing good. I gave it its own space on a top shelf, kept it clean, replaced the batteries quickly and carefully. Perhaps, I should have questioned the seller because the description is "2021 Model." I could find no indication of manufacture date.  Caveat Emptor.
