Mcondon, much worse has been said of the performance of many commercial products than your comments above. I have absolutely no problem with you sharing your opinion and experience for better or worse--it is why I read the comments in the first place. You clarified your original post and cleared up the misunderstanding about "material value", which was my only issue.
Products like the Diamondback and others can never pretend to offer the perfect solution for every application or every system--no matter how much effort is put into making them. They are after all only one part of an overall electrical delivery system in which many variables often come into play.
This is why we use dealers who offer evaluations. If anyone feels stuck with a product that does not work for them, I will always "go to the mat" to help get the products returned or exchanged when bought through one of our dealers. Feel free to contact me if I can be of any help.
Regards,
Grant
