Holds up well after recommended break-in procedure. I don't see much noise from them. When I installed them I put anti-squeak material between the pad and the gasket and outside the gasket. Not sure what's going on that other people are complaining about being loud. They say they're not recommended for everyday driving, but I tend to drive confidently, so I bought them for their supposed resistance to warm fade. I haven't tested it yet, but am satisfied so far. I would be interested to know how long they last.
