I didn't see a big difference in the smells. I have it for a week. I will give it a little more time. Personally, I believe baking soda does a better job.

I bought it because my Whirlpool refrigerator was collecting mold where the shelves were placed on the rails above, and I had to constantly remove the shelves and clean the refrigerator. Since I bought it, it has never collected mold. I have had it for 2 months already and I am very satisfied.
