I have been mailing trash cans back and forth to simplehuman for the past 6 months getting warranty repairs. First one worked for around 4 months and the other two were DOA. Waiting for my 4th replacement to arrive currently. I wish I never ordered a smart trash can, the thing has a mind of its own. First one opened and closed and slammed whenever it wanted to. Second one didn’t respond. Third one doesn’t do voice commands so I can’t get it to stay open. Factoring in the amount of time I have spent babysitting and following up with the warranty department only to get dead units, and transporting trash cans back and forth with special trips into the office during covid to print shipping labels, this is by far my worst purchase. I just want a refund however I am told that is not possible even though simplehuman cannot honor their warranty by giving me a working unit.
