Product review (5 stars): Great quality!
This ducting is awesome, it is better than the ones at the brick and motor stores, feels real sturdy. I needed fifty feet of ducting in the attic from the bathroom to the outside wall and this ducting fit perfectly, no tearing or anything. I had to go around things, and connect to multiple pipes, go up and down a bit and this ducting just works flawlessly, it's awesome!
