Query: Huge disappointment

My favorite diaper system was discontinued, so I used just a trash can for a while and finally I couldn't stand the baby's room smelling so bad that I broke down and bought the diaper genie II (after reading all the reviews). I was so excited. I set it up in two seconds and we were ready to go. After 4 diapers and only one day of use, every time I opened the lid to push another diaper into the pail, a horrid smell came out of the pail. I emptied the pail the next day and even when it was empty and I put my first diaper in it, there was the smell again. I even put baking soda into the bag, and nothing helps. I nearly gag every time I open the pail. I would return it but I stupidly threw the box out already. What a waste of money! I'm sure it would work fine for newborns who drink breastmilk, since their diapers don't really smell much anyway, but my DD is a toddler. I am totally disappointed. This product is a rip off.
