using them for about a month now. I really like these cans. My husband was worried that the sensor would not read the movement but besides the sometimes few second delay to open they work great. I recommend not putting them in a high traffic walk areas because you will get tired of them opening for no reason besides you walking by. (it happens to me and all i think about is if Ill be replacing the battery sooner). The battery is not a big deal. Each take 4 "d" so 8 batteries cost $10. So far so good.
I shopped around for a long time before making this purchase. I am very pleased I did. These cans are high quality and priced way below the well known big box stores. I love the sensor function and they have worked well for some time now.
