I've had them in my truck for 2-3 years. Through many miles and tons of off-road time (and some very harsh wheeling) on desert and alpine trips, they've held up just fine. The only time I had an issue was when coming down a very long, steep grade (Sonora Pass in the California Sierra Nevada) with about 1,200 lb of cargo in the truck. I started getting some pretty nasty fade and had to pull over for about 20 mins to wait for everything to cool down. That being said, the same exact thing would have happened with any near-stock-size pad+rotor setup, so it's not a fault of the product itself.
Pros: held up well, good for off-road
Cons: fade on steep grades
