You don't needto convince meof their devistation, I want to hear if anyone has experienced failure , Im tired of hearing the arguement and arguing that issue with no real solid evidence or record of it. I mean I probably won't go out and buy em, but I will no loger argue that they fail to open if they in fact do open. so who has had a bad experience with the mech heads, it doesn't have to be a Rage head....
