One of three units was defective, but at a third the price of a new port replicator, I figured it was a safe gamble. Seller promptly sent a replacement. Given the amount of dust on the unit, I suspect these are more used than refurbished. Also, while an AC adapter is displayed in the photo, these "refurbs" do not include one.
