      Sellers should use caution with this buyer. Provided an underserved “neutral” feedback, claiming my item was not in new condition and had damage when the item was absolutely as described, in the exact, new, never used condition as per the ad…and in the packaging I received it in from the manufacturer. Did pay promptly, though.

      This is the kind of dishonest seller that hurts eBay. Sadly there is nothing I can do to rectify the situation. Simply put he is lying. Ebay can't protect everyone from dishonest actors. My feedback from other sellers speaks for itself. Caveat empor.
