I don't see what this has to do with anything. The regulators were sold with "free parts for life" and a lifetime guarantee, is it too much to ask that they stand by their promise?
I do not disagree with that statement. But how does getting rid of "parts for life" build good relationships?
I left the US and settled in Libya full time circa 2004 so I am not very up to date on how they manage the warranty in the US since then but did they just annul the warranty for existing customer overnight?
