This is a Weizhi 6 outlet passive power conditioner. It is made from a solid billet of duraluminum. The top plate is made of carbofiber. All of the highest quality. Read all the great reviews. Though I rated it an 8, to err on the safe side, it is in superb condition.
Buyer pays shippping, about 10-12 pounds.
