Good solid connection, right size for the BMW battery cable. The ends of the plastic case appear solid at first glance, but they're cut into strips that form a shape around the wire, which helps keep dust out. also has a sticky gel inside that wraps around the metal joint giving it more protection and insulation. I used it to install a new terminal on the positive terminal of my wife's X5 battery and have peace of mind thanks to the large protective cover. All in all absolutely recommendable!
