If the foot-lever works, I think I can forgive the relative fuglyness of the bin. There is quite frankly nothing more disconcerting than trying to put garbage through those awfully filthy covers. I don't know why they decided to use plastics - I suspect it's cheaper and the components are easier to mass produce and replace. Like trying to clean a graffiti-covered stainless bin; all you need to do in this case is pop out the old cover and put in a new one without worrying too much about cost.
Ditto fiendish's comment re: all is forgiven if it made people more willing to put garbage where they belong. Still think we need a bigger stick though.
