The feeding column is made of sturdy plastic. The column can be easily filled from the top. In the opening the lid and adding the feed from the top of the column. The Feeder holds wind and rain was not that the food falls out or wet on.The column can be stuck on a pole or hanging. The bracket for hanging is stable and robust. I hung on the arms of my window boxes fixing the column. And so far it has withstood wind and weather. The bars are so long that the little birds can put in a good mood. The openings are so large that the birds can easily peck purely with its beak. I have filled the column with chopped peanuts and the birds love the column with the peanuts. From me a strong buy recommendation.
