Review on 13-Piece Dryer Duct/Vent Cleaning Kit, Lint Remover | 24 ft Extension | Synthetic Brush Head | Use with/without Power Drill (12 Rods + 1 Bush Head) by Daniel Steele

I lengthened it with only 4 sticks and it was so fragile it couldn't go through the vent pipe. Came in a box. He had no documents, no name, no label, no instructions. It is intended for use with a drill. It was too thin. I could only use it until I hit the first 90 degree angle at about 4 feet up. He cleaned the dirt and lint that got into the vent about 2 feet up. I would not recommend that. I would take a more expensive brand. The one that arrived had no name and was definitely a cheap fake; maybe even needed.
