Not only is he complaining about it. He wants to send it back to me, after it has been damaged by fedex, he's had it for over a month, won't file a damage claim or even consider the piece was factory installed, opened it up, and wants all his money back.

The unit was factory assembled and the piece has a perfect reason for being there. I told him I thought it was a factory assembeled piece put there to keep the batteries some moving around. He told me I was a a-hole and to f-off and die.
