I bought this to replace a broken hose on my Shark Navigator. It was very easy to install. This hose does not have a pressure relief like the original hose for my vacuum cleaner. The material of the hose also seems to be of lower quality. It stretches very easily, which is both comfortable and uncomfortable. The hose is easy to extend to get where I need it, but it also tends to drag along the floor when attached to the vacuum and I have to fiddle with it to get it properly in the vacuum's mount sits. Vacuum. I have a feeling this hose will probably last a year before I buy another replacement. It will crack/break sooner or later.
