Very cheap but doesn't leak. I don't like it though because it will only stretch about 10 feet before it wants to drag the compressor across the garage. I don't like standing close to a noisy compressor so I replaced this with a standard 1/4 inch PVC hose soon after I bought it. At only $6 though it will do the job and dirt cheap. Just wear ear protection.

Works just like a air hose should the brass threaded ends are pretty good (still put on some telfon tape to stop any leaks none the less). Line hasnt sprung a leak yet using it on a 150 psi home compressor so its pretty decent. Self coiling is a bet of a joke it just raps up on itself then you have to spend some time untangling it but for a short airhose to blow down the workshop or put on a air tool it works. The hose might wont take being crushed so dont run over it or step on it.
