Product review (5 stars): Works!!
Bought this last March when I bought a second hand fridge. The freezer of the fridge had an odd odor to it. The previous owner must have stored some home cooking gone bad or something. Anyhow, the smell was strong enough to change the taste and smell of the ice cubes, rendering them unsavory and unusable. If I had known, I wouldn't have bought the fridge. Luckily I found  this freezer deodorizer on amazon. It works!! Along with the deodorizer for the fridge, these two products have eliminated that nasty odor. In fact,they worked so well that I forgot about the odor and never even wrote a product review. I am supposed to replace the product every 3 months but I never did and the bad smell did NOT come back at all. I am very very happy about it. Otherwise I'd have to sell the refrigerator. Thanks Whirlpool!
