This unit replaced our first one, which was purchased just over a year ago, and only recently the lid started rapidly closing immediately after opening about 50% of the time. Talked to the help desk and they arrange a replacement and return for the old one promptly without any issues. The new one works better than the old (seems they've modified the motion sensor search pattern a little) and we couldn't be happier. It's still the nicest dual can on the market, a bit overkill you could say, but from the first time my wife called out "open bin" (it works with "open bin" btw simplehuman, should you have any prospective British customers..,) she was sold. We have several other simplehuman products and they've always either been top notch out of the box, or promptly replaced under warranty when not. We appreciate the excellent customer service. Thanks!
