Brome's patented Squirrel Buster technology, when set up as directed, can be squirrel proof. The outer "cage" is weight sensitive so when a squirrel gets onto the feeder, the "cage" will shift down, blocking access to the seed ports. Plus, their negative grip tube prevents squirrels from grabbing the wire hanger with their hind legs in an effort to bypass the weight-sensitive perch.
The unique cage design also provides a great surface for the birds that prefer to cling instead of perching (nuthatches, woodpeckers).
Holds up to 1.4 quarts of seed
Includes a 2 year factory warranty.
