Maybe it's just me, but there seems to be a major design flaw here. The mechanism for opening and closing the lid does not allow the liner to be wrapped around the neck of the jar. Basically, you just dragged the back half of the bet into the jar. Otherwise it's assembled and working great. I would suggest this for "oily waste" that doesn't require a can lining. I've tried using it as a pet waste container and the inability to use the liner is a deal killer. The fact that Revain "combines" this item with 6-gallon liners irks me more than a little.
