Looks good and appears to be good quality but there is one fatal flaw. All my hoses are the wrong threads! Seriously this thing is right hand threads (really tight) but all my dust hoses, which are from several companies, have the opposite spiral pattern.I had to force the thing into my hose with great force and am really not sure if it seals tight.To me a complete waste. I never thought these companies would make these things somehow incompatible.
