I got this one to replace a smaller one - 30 gal I think - that I'd had and loved for many years. It was just the right size to fit under my counter, but the when hinge broke and I wanted to find an identical replacement, seems you don't make that size any more, so I ordered this one. I looked at other brands, most of which were less $$, but I knew I wanted another simplehuman. It works beautifully, but sometimes the top gets stuck when it hits the underside of the counter. That's my only complaint.
