Overwhelming O3 smell that permeated plastics and liquids in fridge
I never got to the point of determining if this really made the produce last longer in the refrigerator because our family could not get past the O3 smell emitted by this machine, so two stars for the fact that the product was easy to setup and functioned without any issues, but that's it.  These devices are the same technology as the Sharper Image Ionic Breeze machines that mainstreamed about 13 years ago.  The first thing we noticed was the strong O3 scent upon opening the refrigerator.  I immediately checked all of the plastic and liquids to verify the same smell and of course the O3 had permeated into those, which is quite common with these devices in small spaces.  Several days later we can still smell the O3 in the plastics that were in the fridge.  There is scientific debate as to whether devices like these actually create more harm than good in small spaces.  Although these are not O3 generators, the amount of O3 emitted within a confined space over time may be considered problematic.  I recommend reading up on O3 and how these devices are viewed when operated in small, contained areas.
