Sparky I see your point in regards to backing the product as it pertains to the AFCI. I was just gerneralizing on cost and profit. It will certainly be interesting to see where this goes. I suspect there are probably many of these afcis installed at a huge cost to homeowners. In my mind if you remove this now you are admitting a huge mistake and misrepresentation of the product which may get the lawyers scrambling for some class action on the behalf of duped consumers.
