Comments about Gutter Brush: This brush was perfect for what I needed: extra reach for brushing light debris from the gutter screens. It's probably not substantial enough to dig out heavy gunk from deep in the gutter, but I wasn't expecting that. It did just what I needed it to. Very lightweight but the brush held it's shape when I pushed on it.
