I am a "metal is real" kind of person and I NEVER thought I would ride carbon wheels. When these came up on sale I was convinced to give them a try and ....WOW. They delivered big time. I rode them hard for six months in Sedona, AZ - giving no consideration of their carbon construction I square edge hit them on countless rocks and every time I unpuckered from thinking they were done for, well they just kept on going. I got one pinch flat, but the impact from that hit left me thinking the rim was ruined. Not the case. Didn't even knock it out of true. I am beyond impressed with the durability, but I haven't even mentioned the great ride quality. I thought they would ride way harsher than my aluminum rims, but I was mistaken again.
If you are on the fence about carbon wheels, don't be. I'm converted.
