Everything about this feeder is great - except for just one thing. The chain by which the feeder is suspended is fixed inside to the plastic, and runs upwards through a hole in the metal rain cover. This means that there is a hole around the chain. Rain will enter through the hole and soak the seeds inside. They will then become mouldy. A ridiculously poor design. save your money, do not buy this unless you live where there is no rain.
