I know we've been through this Al, but your last post really takes the biscuit
"Out of curiosity" you called ON_X to find out about an installation problem in an individual case?! Many people on here have an interest in the valve and many have it implanted. But no-one is any way near as obsessive about it as you.
Every/Any time a person puts up a reasonable objective argument that in any way is a con of the ON-X valve you do everything possible to hammer home an explanation to the contrary. And often, that is that.
I accept that you are NOT a rep. for ON-X, but I do find your need to put a counter argument to everything said, a little strange. Old ground I suppose.
Maybe I just can't resist having a pop at you, I don't know
I can understand that perhaps you do truly believe in this valve and have a mammoth amount of info to back this up, but you have to admit you do use a hell of a lot of ON-X's in each post!!
