Easy to clean- twist and clean (patent pending) easy-clean bottom comes completely off for easy cleaning. No screws to mess with. Easy to hang- looped wire hanging cable included (150 lb test) and attached. Holds cap so you don't have to wonder where you put it. Feeders come completely assembled (in beautiful open view box.) Take out of the box, hang in your yard, and watch how fast the birds are attracted to the patented Spiral Perch.
