We have 2 machines and this is our 3rd hose, in 3 years, so yes, they are durable. We would not have even needed to buy this one if we hadn't noticed a small hole in one of them (caused by a pet, we believe). Much better than using any type of cheap foil hose

This arrived packaged extremely well and included new clamps. I am using this as an exhaust for my laser engraver.It did take some effort to get it to fit onto the 4 exhaust port, and once installed I almost did not need the clamp. Although I have not stretched it to its full length, I think that the 8 feet is 8 feet in a strait line, with no margin for error. If you need to bend it or account for the attachment to the ports, order a longer size.That being said, this is a heavy duty flexible hose. I don't have to worry about a stray ember from the engraver melting a hole in the material. I'd buy this again.

My only complaint is that I wish the inside diameter was 4 1/4” instead of 4”. It can be difficult to slide over the pipe on your dryer or vent. Otherwise it seems durable.

These are snug to put on. Got to be careful when putting on or taking off. The black finish looks really nice on our dark dryer.
