That's the third feeder I bought Woodstream, and I must say I'm glad. After several months there is no sign of degradation, and the birds love them. I put some small stones close holes in the bottom, just to make the seeds do not come in too large quantities, - that it would cost me a fortune, and also the birds are fed and waste less. I put 4 stars and not 5 because I think this and a little too expensive!
