Love the hot cylinders as squirrels leave alone. Cardinals, Carolina wrens, chickadees, tufted titmouse, woodpeckers, finch, nutchhatch etc all enjoy the seed, My first 6 bluebirds came due to the meal worms inside. No mess as juncos & birds eat any that may drop on the ground. Lasts weeks!
Great value & nice to no longer need to constantly fill feeders,
