While the gutter itself is not clogged, the custoemr reports that pretty much zero water is getting into their Leaffilter gutters. Investigation shows that the mesh is separating from the filter body in this area and 5 others because this is a product that is assembled "in the field" so there's no quality control. It's also plugged with asphalt shingle oil and has a bunch of debris piled up on it in many places. Bummer that it does exactly what they said - no gutter clogs - but no water gets in either!
