E311,

Although you make a compelling argument, the customer still has control of what they do with their equipment. We can only try and use our knowledge, experience and reasoning to try and influence their decision. Our last choice is to walk away.

Thank you for sharing your experience in regards to the reverse phase relay. Even if you can provide the proper documentation to contradict their claim! You still get the full experience of the law suit. Yes, I've shared that same road.
