Top Seller in the store and Mike's favorite squirrel-proof feeder.  This feeder has a weight sensitive shroud that closes the seed ports when squirrels and large birds land on the perch.  Made from rugged UV-filtered ABS and Polycarbonate resins and powder-coated aluminum components. The hangers, springs and fasteners are stainless steel.  This feeder can be easily disassembled by hand, without tools, for cleaning and is even dishwasher safe!  It has exclusive seed tube ventilation.  As the user, you can adjust the tension to your requirements, deciding what weight bird will be able to successfully get their seed. 

The cardinals prefer the thick-textured perch on this feeder.  The "Cardinal Ring" on this feeder allows the cardinals to eat facing the seed from a secure and comfortable perch.  On most other tube styled feeders, cardinals cannot bend their necks enough to reach the seed source.  Definitely Cardinal-friendly.

Tested in Mike's backyard, this squirrel proof feeder really works well.  Love to see the cardinals come to this feeder and eat with ease.  Squirrels don't have a chance on this one!
