I bought the feeder from Rentacoop off amazon. The lid would not seal on. I asked to return it and exchange it for a non-defective one, but Rent-a-coop didn't respond. Then I complained to amazon, and they offered me a refund/return. I was happy I purchased from Amazon and not directly from rent-a-coop. After I wrote a scathing review, Rentacoop sent me an apology. But obviously, they are having some issue with their quality control
BTW: despite the name, rent-a-coop, they often sell products (not just renting them.)
