This trash can is better than other sensor trash can models I had in the past. First of all, it doesn't need any battery. It includes an AC adaptor so it works out of the box. If I want to use in an area that doesn't have an outlet, I can still use optional battery power. But it is just an eco-friendly feature that I don't need to spend money on batteries. Secondly, the other brand sensor trash can I had broke after just few months of light use. This one seems a lot more durable. The stainless steel can is thicker and the lid's hinge is stronger.
