"I bought two of these for bird food. They really look good. I keep them in a garage, and after reaading others reviews, I would not leave them, as tempting as it is, outside. It is regrettable that the manufacturer does not sell replacement tops.
I, however, discovered another deficiency which means that I won't be buying any more. When you stack them if the top container weighs at least 5 or 10 pounds more than the lower one, it compresses the lower one so that the screw top will not turn. This is an eminently fixable problem by the manufacturer, merely by putting in a few more layers of the plastic, i.e., thickening it, in at least 4 vertical sites.
It is too bad that they seemingly inadequately tested it before releasing it and that sellers are unaware of this, and the other problems cited."
