I bought this thinking it was a wonderful design & idea. It was pretty easy to assemble & use. However, once the diapers fill up the bottom of the bag then the claw-like contraption that is supposed to seal out the odors doesn't close completely & you get the smells. If you continue to use the pail after filling the bottom of it (like I just mentioned) then the diapers start to pull on the bag & that causes the spring that holds the claw-thing in to pop out thus defeating the odor control purpose. Putting the spring back is no easy task. If you manage to do that the claw-thing permanently doesn't close all the way. I went through 2 of these, with the same problems, before I resorted to a regular garbage can. I never did see any refills for the scented disk that goes in the top, either. I have no idea where anyone would buy them. I'd suggest finding something else to use instead.
