Yeah, some years back. They sort of work, nothing short of stripping all fabrics from an interior will get rid of cigarette, cigar, and some other odors ( don't ask )..
They can be dangerous also, need to make sure car is locked and secure while ozone is running. Also found that on a really hot day with windows up, smells will re emerge..
Don't recall any brands, talk to a used car dealer if you happen to know one close by.
