Great customer service, good build quality but has a major design flaw. The slotted holes are too large and allow squirrels to lift the cover off of the feeder. I have another feeder that is similar but the holes in the top cover are very tight and squirrels cannot lift the cover on your competitors design. I've got to come up with a way to lock the cover down, probably will drive a dowel into the slotted holes in the cover.
