This feeder is made from materials that look & feel like my squirrels won't be able to damage it, which is my main problem. It's easy to put together with all necessary parts provided, and I was able to easily shorten the hanging cable by knotting it loosely at one end. I would happily give it five stars, but I have problems with the overall design. I feed only sunflower seeds, and the sides of the trough areas are not tall enough. I'm finding a lot of uneaten seeds on my deck and the yard below. The cutouts in the plexiglass sides that allow seeds to fall through from the main chamber are too short for sunflower seeds too. I had to jam a small rock under each side so seed will flow freely. My main gripe, though, is that I feed year round through rain and snow, and the eves aren't long enough to stop the trough areas from filling with water or snow. And there is NO way for that moisture to drain out, so it sits and spoils the seed. My only options will be to find some sheet plastic and attach it to the roof to provide full coverage, or else drill drain holes in the troughs, and cover them with window screen so they won't clog. I'm not sure that moisture won't settle and mold in the drain holes either as there are small cavities in the floor material. I'll have to go with a roof covering I guess... So, it's very well made and sturdy, but is not exactly what I need in a feeder.
