I really haven't made up my mind yet on this trash can. It's very attractive, and seems to work fairly well. I guess I'm a little impatient waiting for it to open at times. My husband gets a kick out of it, so I guess that's important. It takes 4 D batteries, and I've probably had it for almost 2 weeks I believe. It doesn't sit where we walk past it, so we don't have a problem with it opening all the time. The opening is fairly large, so that is a plus. The 4 star rating is just due to my impatient nature : /
