The consistency, quality, and content of the seed cylinders are the best I have found. I have used 4 other brands of cylinders and none hold up to the hammering by woodpecker, weather ( rain and snow) and assaults by magpie and jays. The cylinders are packed with a variety of seeds, nuts, worms and fruit depending on the selection and I have used all of them. I won’t shop anywhere else and I’m a member of Cornell Lab of Ornithology and an avid birdwatcher.
