Very well designed, practical, solid trash can. It has a mechanism to close slowly and quietly, good traction so it doesn't move when used, an interior mechanism to keep it open whenever you want, and a plastic liner to facilitate trash removal. The smaller can is the exact size of a grocery paper bag. so grocery bags can be used for lining. If you use Whole Foods bags for lining, buy the middle size can. Overall I am extremely satisfied with this purchase.
