Perky Pet Hummingbird Feeder For Hanging Baskets And Planter Boxes Works For Me And My Hummingbirds. The stick holding it did not hold the weight well for me. I used a differant hook and hung it on a tree houseplant that is outside. I watch the hummingbirds come and drink and see the air bubles rise up in the tube so I know they are getting their fill. About 5" x 1.5". Bee Guard.
