Review on Small Size Ozone Generator, Dailyart Portable USB Rechargeable Ozonator for Cars Refrigerator - Odor Removal Machine by Julie Terrones

This is a low power ozone generator for small spaces like a refrigerator or car. I've only used it in the fridge so far and it seems to extend the shelf life of food. Although I haven't done a formal test, I see that in the few weeks I've been using it, fruits and veggies that tend to go bad if you don't use them quickly seem to last longer. It's good. The only thing is that the number of options for use and installation is limited. Otherwise, it's a reasonable price, so I'd recommend it.
