feeder will not stay level, the bottom of the flat so it is like trying to carry water in a pizza pan. I have had the wind blow it off of the hook twice (in one week), the last time it broke hangar rod threads out of the plastic part. I now have it mounted on a pole and it works well. I wish I would have not wasted my money feeder. If you get it for under $3 including S&H and pole mount it, it may be worth it, not for me.
