Amazon.com Review:
This practical bird feeder by Opus features "chew proof" copper armor, perches on two levels, and six feeding stations where birds can devour up to three pounds of sunflower and mixed seeds. The body and tray of the feeder are constructed of sturdy plastic, and the feeding stations feature an outer layer of copper. You can easily remove the top of the feeder, a copper half cylinder, to refill the feeder. A quick-release plug on the bottom of the feeder simplifies cleaning, and the bottom tray can be removed to discourage larger birds from feasting. A mesh wire loop is attached for hanging. This tube feeder comes with a lifetime warranty and measures approximately 19 inches high without the hanging loop.

squirrels thought this feeder was delicious...:
This feeder is made of a plastic tube and plastic bottom. Pretty standard stuff aside from the thin copper top and thin copper bands near the openings. The quality wasn't what I'd imagined, but my expectations weren't that high when I ordered it. I was looking forward to the copper aging and eventually looking pretty cool. There's a distinct possibility that the squirrels in Maryland are just darned mean, but they disassembled this thing in roughly 4 hours. The feeder openings, to their minds, weren't big enough. So, they expanded them. When the copper got in the way, they just tore it lose. The openings became so sharp and jagged that I feared for all my critters' safety. The service life of this feeder was less than 2 days. Do yourself a favor and spend a little more on a good quality feeder, like one from droll yankees.

Decent design, but there's a better choice.:
The manufacturer makes this same design with stainless steel top, bands, and perches, which the squirrels have been unable to damage. The stainless steel is a lot harder and tougher than the copper. Removing the bottom tray makes it more difficult for the squirrels to eat, and hasn't bothered the birds. I've had everything from chickadees to red-bellied woodpeckers feeding from this feeder, with all perches full and a waiting line on the railing of my deck. Even the cardinals (for which the perches are really too short) have learned to use it. In short, the design is okay (certainly not squirrel proof), but I'd opt for the tougher stainless steel model. It may not look as nice to begin with, but it will last longer.

The feeder is attractive,relatively easy to clean and it attracts an assortment of birds.The usual assortment is, doves, finches, cardinals, goldfinches,titmice, nuthatches,chickadees, grackles. I enjoy it very much, but sometimes the squirrels manage to get on the feeder. I hung it between two trees on a steel cable, because the squirrels chewed the original telephone wire cable that it was hanging on. They also manage to tight rope walk across the cable, but I strung up some film containers and AOL discs (which keep coming in the mail) and that deters them somewhat.
