Query: Disappointed with Diaper Champ

I used the genie for two years and pregnant with my second child, I read the reviews of the champ and was excited. After two years, the plastic of the genie soaked in the smells. With the champ, I was very disappointed because after two days, I need to change the champ or it will smell up the house. I could leave diapers in the genie for up to 7 days before changing it out. I only use the genie/champ for poopy diapers. Maybe mine is defective...I'll never know. I am going to sell my champ on e-bay and buy another genie. The fillers with the genie are a pain, but worth it.
