I stumbled across this item in a store and bought it, not expecting much due to the low price. This has performed so well I searched for the source online to buy more! Why is this a great bird feeder? First, it allows you to reuse a two liter soda bottle. Second, the design allows birds to feed while having minimal seed drop. I don't know how the design manages this, but with most of my other feeders lots of the seed ends up falling out. Probably most important, the squirrels don't seem keen on messing with this. Maybe it swings too much when they try to jump on. The only thing that isn't perfect is that the knot which holds the string has slipped through over time, causing the feeder to fall. But we were able to resolve this by tying a screw to the string. The screw hangs perpendicularly to the support string, therefore providing a base that can't slip through. I highly recommend this feeder. It should be in every feed and pet supply store.
