I needed a replacement dusting brush for the ceiling and hard to reach areas on my balcony since my old brush literally bit the dust. Not a good Idea to leave in the sun for several years. They did not have the same brush at the Home Depot that I had purchased in the past so I purchased this one. When I went to use it the end of my commercial painting extension pole would not fit into the handle. I at that point considered returning the brush but then realized that all I had to do was to saw off the handle on the brush back far enough to reach the threads and walla! The Unger Cobweb and Corner Duster did exactly what it was designed to do and now no more unsightly dust and webs.
I put this brush on the corresponding telescoping pole to clear snow from my little satellite tv dish. It works exactly as I had hoped and I will use it to clean other things I cannot easily reach in the future I am sure. It seems study and a good size for different uses.
