Product review (4 stars): Helped get the odor out of the freezer.
We had left fish in the refrigerator and before we knew it, the odor permeated both the refrigerator and freezer compartments.  Cleaning, baking soda, coffee grounds - nothing worked.  Within a couple days of putting this deodorizer in the freezer - and the comparable refrigerator one in that compartment - we were odor-free.
