Review on 🧹 Efficient Dryer Duct Cleaning Kit: 10ft Flexible Lint Remover with Power Drill Option - Includes 8 Rods & Synthetic Brush Head by Keith Mertz

It was cool. It bends, but don't expect it to bend 90 degrees as it doesn't. I hooked it up to my drill press and it cleaned the dirt out of the dryer exhaust. Make sure you have a vacuum or something to pick up lint or dust. Otherwise it will accumulate on the outside of the pipe. It's enough to get to my house's air vents, but not far enough. So I find another set and expand it. The caliber is large enough to last about 30 feet I think. I would recommend keeping a pair of pliers handy if you are using a drill press. Rotating the bars only compresses them more so you need something to really hook them to rotate and separate them. I'm happy with that. When tying 30 feet of string together, I don't want it to fall apart halfway through my vents.
