Not sure if its mcgard that rimstyle supply with their wheels, but if it is then yeah +1 they're sh!te. Can only undo/do them up a few times before they're fecked, and the splines chew off. The tool doesn't fit the bolt square on, it wants to slip right off at a dodgey angle. Load of sh!te. And no I dont torque them up too much, I only nip them, but a few months later when you come to remove they're a little bit siezed and take more torque to undo em, that's when they start twisting the splines. Dog sh!te
