Query: Nonexistent Odor Control

I'll say one good thing about this product: it's easy to use. For a while it seemed to control odor fairly well, but as my daughter got older and her waste got smellier, the Diaper Dekor showed its weakness. Her whole room smells like an outhouse. I've had enough, and am moving on to another product.
