Query: Really bad smells

I just read the great reviews about this product and am very surprised to hear people don't have problem with the smell. I have had the Diaper Champ for 16 months now, and think it is pretty cost effective, compare to the Diaper Genie, but frankly I am considering buying something else, cause it really does not keep the odors in. We have to change the bag every couple of days, when it is not even full because it is pretty disgusting.So just because of that I would not recommend it.
