Still a prototype this product manages to resolve most of the issues facing a bird feeder. The design is tough for squirrels to dig into and raid, is easy to refill, keeps the feed contents dry, is completely idiot proof to install, and the design also claims to be attractive to birds, especially blue jays and cardinals. But wait, there is more….the tear drop shape is perfect for shedding rain and wind easily, the manufacturing is straightforward, and the materials and shipping are environmentally low impact. Wow, loads of great details in a design that would usually be overlooked.
