I've got a SimpleHuman 40 liter plastic slim step can (http://www.simplehuman.com/40-litre-slim-step-can-black-plastic) and the lid will not stay on. When I press the foot pedal the cover pops off. Have examined the cover along with the hinges on the trash can and there does not appear to anything wrong with it. Has anyone seen this before?
From the reviews of these Simple Human trash cans at Amazon, this seems to be a complaint many have reported. It sounds like a design flaw. How long have you owned it?
