My first sewer hose took about 2 years and had a leak. I liked them because if you stretched them, they stayed as long as you stretched them. My second set was a different type that gave a bit, so it always had some tension and wouldn't sit on the stand if it dented, but otherwise worked fine. Now that I have a sore thumb connecting and disconnecting hoses, I bought Camco wrenches to help. Unfortunately, they only fit barbed hoses so I bought a new set of these.
