Songbird Essentials Suet Saver Upside Down Suet Feeder, Rigid Plastic Case with Suet Cage Bottom, Holds One Bird Seed Suet Cake...

Woodpecker love this feeder, BUT starlings do too. It doesn't deture them one bit, the only advantage is, only one starling can eat at once, not 4 or more like regular wire suite feeders. I'm keeping it, but only because less starlings can eat the woodpecker food.

Don't waste your money, as this doesn't stay put once it's hung, rather falls apart and to the ground. Poor construction.

Works great; truly makes suet last longer. Product update: After two years of Winter-only exposure, the plastic (main) part became quite brittle and fragile. Side broke out a separated when I took off the wire cage to load a suet cake.Obviously not a good type of polymer for this application.

I was skeptical, but got it to try and deal with a grackle problem; the grackles did figure it out relatively quickly, but weren't nearly as effective at clearing it out (at one point one of them was hanging by the beak from the bottom rail, before letting go and flying off) while the woodpeckers were perfectly content with it (even continuing to feed while other birds flapped into the plastic part.) Eventually the grackles moved on, but even at the peak it reduced a 2 blocks/day feeding to a block lasting 2 or 3 days (peak summer in New England, woodpeckers and nuthatchs and sparrows, no starlings though.) I also haven't seen the squirrels swinging on it - they have other food sources, so I suspect it's less about them having trouble as finding it less "fun" to swing on... Even without those benefits, I find it a little easier to load than the classic cage, because a classic cage ends up greasy *everywhere*, while the plastic part of this one stays clean (there's a bit of a knack to opening it, where squeezing the plastic part helps.) My one complaint is that it's kind of ugly :-) Adding some decoration (flowers? leaves?) to the plastic part would help, if one were crafty or had a good set of stickers.
