Requested for a longer chain and seller obliged. However, the wire cable is a different colour from the original cable and thus do not match. Otherwise, it's a good product. Mailman did not inform me of the delivery and simply left it at my door step. Not very professional of the mailman. Maybe the seller can feedback to the courier service on this as this is not a cheap item and shouldn't be simply left on the door step without getting buyer's consent.
