Great product

I bought a second-hand air horn the parts on it or pretty bad and it did not have a air gauge on it so I bought this and a tank and it was very easy to hook up just make sure when you buy your tank you get enough holes in it where you don't have to put sitting everywhere. But other than that everything worked great recommend to anyone.
