After 18 months, our original Diaper Genie 2 had basically taken on the diaper smell and couldn't be cleaned anymore. With Baby #2 on the way, we decided to try Diaper Champ. Big mistake.Mechanically, it worked soundly, so no problems there. However, with every turn of the drum a "puff" of foul, diaper stink floated up.My decision to return it was made immediately upon opening the compartment to change the bag. The bag just sits down inside, but is wide open. The odor immediately filled the baby's room, and several adjacent ones. With eyes watering, I grabbed the bag, tied it off, then double-bagged. Fortunately, we could a few open windows and turn on a fan to disperse it.I hope I can get my money back.
