Sooo much easier to clean and maintain than traditional hummer feeders with bottles. Just snap off the lid and wash. Better visibility with no bottle to block feeding hummers from view. The feeder is leak proof and the ant moat can be filled with water to block crawling insects. Six feeding ports,16 ounce capacity with nectar level engraved on the side of the bowl. Brass hanging rod screws into bowl. Made in USA.
