For DD we've had a Diaper Dekor for the past 3 years. For the most part we've liked it but the plastic has absorbed quite a bit of stink. For DS I'm considering buying just a regular stainless steel trashcan but am worried that it won't trap the stink as well when throwing diapers away since there's no trap door. For those that use a regular trashcan, do you think it holds the smell pretty well?
