Prior to getting a fully functioning garbage can, we had 2 incidents with SimpleHuman cans where the batteries would get zapped overnight and the voice command didn't work on either. The third time was the charm, now this one works for both voice and sensor, and we like the look and size. My husband especially likes the way the top opens, our old sensor can was great but the bag would snag every time a full bag was pulled out of the can, and it was super frustrating. The way the layers of the lid work on this one it's not an issue and we also love the ease of pulling out the recycling bucket, previously we had our recycling stacking up on the counter next to the can and had to make trips multiple times a week to take them out. Giving this 4 stars mainly because of the terrible experiences getting non-working cans, at this price point it's kind of worrying and we are a little concerned that the life of this can might be short given these negative initial experiences.
