This is an nice looking trash can and a good size for people who do not generate a ton of garbage or have a small kitchen. However, the materials are a little chintzy -- the can appears to be stainless steel, but the lid is silver plastic with a very thin black, plastic lid. It requires 4 D batteries, which seems like a lot of power to move a very thin plastic lid up and down. The movement of the lid is a little jerky; it opens smoothly, but stutters upon closing. It also starts to malfunction if your batteries are not fresh and fully powered. At first I took some batteries out of a flashlight to test the sensor lid. The batteries were not that old and were doing fine making the flashlight work. However, it was not enough power to get the lid fully closed (the lid would go up fine, but wouldn't close all the way). I bought some new batteries and now it closes fine, but it's a little jerky upon closing as I mentioned. The sensor is good -- it is a little over sensitive as others mentioned, and will open if you walk by it. I do think it's overpriced for the quality of materials, and it will be expensive to keep it powered up with 4 D batteries all the time (would be better if it used smaller batteries that you could get more easily as rechargeables).
