I bought this after my old (cloth) hoses finally gave up on me. I pulled them out, and discovered that they were beaten, torn, and cut to pieces. The parts taped to the clips at the top had to be pulled out as well. I got the new kit within 2 days of ordering, and had them installed in under 10 minutes. It was as simple as putting the ducts in the hoses, running the hoses through, and then connecting the hoses to the plenum. The new clips were life savers! My old clips were rusted through, and the new ones held good and tight. The hoses feel very flexible and sturdy. Couldn't be happier with my purchase!
