I am currently diapering my third child and have used a diaper Genie with each one. I probably don't empty it as often as I should (that's due to my own laziness), and I end up throwing a lot of diapers in the trash. Due to that fact, sometimes the diapers sit in there for WEEKS and I have never smelled an odor! I don't know if everybody else is using it incorrectly or what, but it has served me very well, and I intend to continue to use it with any other children I may have! (To all you naysayers who don't believe it works, try reading your instruction manual.)
