Overall, we really like these trash cans, and for the price, are glad we bought them. My only two issues are minor, and some will say too picky, however, they did ask for feedback!
I would have rated these trash cans five star except for two issues:
1. The sensor doesn't always pick up right away, and sometimes we have to stop and waive our hand closer to it. On the flip side of that, quite amusingly, the lid opens frequently when we just walk by.
2. It automatically closes, whether you're blocking the sensor or not. In other words, if we're scraping a plate into the trash, even if we are standing directly over the sensor, it frequently closes onto the plate we're scraping. There is a manual "open" button that stops this from happening, but I do know the technology exists to adjust that with the infrared.
Like I said, two fairly picky points. We've only had them about two weeks.
