In terms of quality, this is easily the best bird feeder I have owned. It is well designed, has sturdy fasteners and components. Unfortunately, the birds have not yet taken to this feeder. I suspect the lack of a perch might be an issue, but it could also be the food. Two suet cakes fit perfectly, but as the perching birds tend to prefer suet, it might be best to replace it with black oil seed or millet. Looking forward to many years of use with this.
