GutterFill® was rated the highest foam insert by Consumer's in the Sept. 2010 issue over Leaf Defier® and GutterStuff®.
American Gutter Filter had no knowledge of this "performance test" prior to testing! Testing was published by a non-for profit Union of Consumer's claiming they are the largest independent consumer-product testing organization in the world located in the United States.
