I ordered this product to secure a foot and a Manfrotto video head. The article contains no thread 3/8 "or 1/4" below and therefore can not be screwed on one foot. CAUTION SO ALL WHO THOUGHT POWER DO !! According to the seller, this is normal and it seems that it is me who has made a mistake ... Anyway, this article is useless to me.
Otherwise, arrived on time and in fact paid by the seller when I reported the problem. 2 * so for the delivery and management by the seller of my problem, 0 * for the product itself, which is not usable for me.
