Query: An Absolute Must!

Put an extremely stinky diaper in here, and you won't smell it again. A friend who bought a different brand complained that she should have bought the Diaper Genie because her child's old diapers permeate the room. My child's pediatrian said plastic bags work just as well. That might be true, but this is so much easier and quicker! They're cheap--buy one!!!
