This past weekend at my wife's certification class, one of the instructors HP 6" hose for her transmitter disintegrated at the metal coupling. The dive shop owner suggested it was from "knock off" braided hoses. I have all dive gear express double braided hoses on my wife's Deep6 reg set up. He looked at them and said they were not miflex and they were the cheaper knock off's. SO my question is; does anyone have any negative impressions of dive gear express double braided hose's?
