This is a great bird feeder if you have a squirrel problem. Our's was so bad, we had given up on trying to feed the birds. We've had this feeder up for a week now and the squirrels don't even try to feed from it any more. We have cardinals enjoying it instead. I also am very happy with the size and appearance. Whether or not it is very durable, only time will tell.
