Irons Your 10713 is very interesting.I had not seen that previously. I think this is a very good indicator of how this product will be adopted. Mistral have tried it , it is easy to assemble and suddenly all the leaks they had with compression fitting disappear - a major boon . So someone else sees it , or hears of it they start to use it and we have liftoff ! I am hoping that Volvo will opt to use it on a new car and then the world will really sit up and take notice !! At long last my decision to sit and hold (and suffer ) is being proved to be correct ......Ladron
