    Item arrived on time and well packaged. Unfortunately wasn't model advertised, and therefore didn't have the USB ports. Requested return through eBay. Return was easy via Royal Mail, and refunded very quickly. No specific communication from seller, but return easy. Item looked ok otherwise, and cable included as specified.
