@bucksnbears I use this to scent treat my jeep. I throw my gear and clothes in and treat everything for 30-60 minutes. Then I rolled down the windows and let it air out for about 10 minutes. As others have said, breathing ozone in enclosed spaces in high concentrations can be dangerous. https://www.basspro.com/shop/en/hme...ASE-eOp29UwPbJ2AUvabJ3vORuDYZ3KwaAoryEALw_wcB
That is weird, I have been using mine for two seasons now without an issue. However, at that low price point it is unreasonable to expect it to last forever. Two or three years out of this for less than $50 is more than reasonable from my experience.
