good quality, cheap, but watch the picture is not quite identical to the box, I can not tell if supporting domes on the piston are identical to the pictures. in my case the supporting domes for "old" vehicles (type 1 Renault Laguna etc ...) it is not said that he will go on newer vehicles without making small alterations !! it would be good that the seller put the type of supported vehicles. otherwise okay seller, he exchanged the box because the box was broken and was missing a piece inside.
