This little guy was the lowest priced best selling ozone generator on Amazon for years
, and highest rated, 4.7 stars most of that time now 4.5 because of some late negative reviews because we ran out of ozone plates and shipped around 30 orders 3-4 days late. (boo hoo) Those Amazon reviewers are sometimes brutal. Anyway, we no longer sell on that US job killing website anymore so let bygones be bygones and move on. So here we are, selling the returns we had over the years. All come with a brand new plate. All work fine. Most were just used one time to get rid of an odor then shipped back for a full refund. What a deal eh? Don't have to rent an ozone generator, just buy it on Amazon and stick the seller with a loss on the shipping and a product they can no longer sell as new. My guess is that most Amazon sellers do sell used items as new to stay in business but that's another story. We didn't because we believe in karma, so we have quite bit of these hard working odor fighting guys looking for a new loving home from someone that won't abandon them. Is that you? If so, then what we have here I believe is a win-win situation! Enjoy.
