I have two kids, a toddler and a special needs 5yr old (obviously not potty trained). While this diaper genie does help with the odor of the used ones, I think it has as much to do with me taking it out more frequently as much as anything. My older guy wears Pampers Under jams (size S) and we have a hard time getting them to fall through the opening. I also take it out every other day now instead of every 3rd day because the capacity isn't as big as the can I was using before. Overall, I can't say it's a big improvement to the small trash can I had before.
