I was really hoping to like this motion sensor trash can more.  The sensor only works about 50% of the time on the first try; other times, I'm standing there waving my hand in front of the sensor about 3-5 times before it pops open.  Sometimes it pops open on its own when I walk by it.  I do like that it has a battery option as well, because I don't have an outlet where the trash can is placed; it uses 4 D batteries.
