content: This is a very attractive feeder, but the problems I have will keep me from buying another.The slide-clip opens with very little pressure - the squirrels pop it open every third or fourth landing.The wire hanger is close to breaking near the slide-clip.The slide-clip is a marvelous idea, but the application is weak.It is very simple to clean. The side panels lift out so they can be thoroughly scrubbed, and once they are out, the inside of the feeder is easily accessible.
