We bought a touchless trash can at Costco about 10 years ago when we first noticed them on the market. We had many issues with that model, which nearly soured us on sensor-triggered cans:1) The batteries were stored inside the lid assembly, so gravity pulled them into the trash (as the cover wasn't strong enough to hold them) unless we added packing tape.2) The trashcan body was easily dented and stained.3) The motion sensor was too sensitive, picking up whenever someone walked even remotely close to it.So we finally broke down and replaced it. This model is a VAST improvement. The only major concern we had prior to purchase is that there are no bins, just plastic rims you wrap the bags around -- so bags are mandatory. We would have preferred a bin for the recycling so we could just dump it out routinely, but we've managed to re-use our recycling bags several times as long as we don't load it up with heavy bottles.Where our old can only had room for one thing, this handles trash and recyclables side by side. That's a game changer in our house, where we used to stash the city-provided bins in our kitchen where we'd trip over them, or else we'd have to haul things out in batches daily. This can doesn't have a ton of room, but it does buy us 3-5 days for recycling and generally about a week for trash. We don't mind getting in some extra steps 2-3 times a week, we just don't want to do it every day!We use 33-gallon bags for trash (as we have plenty of them left over from our past can) and 13-gallon bags for recyclables. Both work great as the excess on the larger bags wraps neatly around the rims. As you can see from the pictures, we put the stickers on the inside of the lid.The sensor is better at detecting motion intended for the can, though it does occasionally open if someone walks too near. We did have an issue after about a month where we thought the sensor was broken. It alternately kept opening without any input, or it would stay closed no matter how much your waved unless opened with the button. We turned it off for about 30 minutes, and just as I was about to contact support, we tried it again and it worked properly. And it has continued to work great for many weeks now. There were a few reviews that mentioned temporary malfunctions, so I'm guessing this was one of those. When in doubt, turn it off and leave it off for an extended period - if that doesn't fix it and the batteries are still good, then contact support.Honestly, I didn't expect to get so excited about a kitchen trashcan, but this makes things so much easier in the kitchen.
