Been riding a tubed pair for 6 months and around 5000km. Not a single puncture, even on some roads with a lot of debris. Still a quite a bit of tread left if the tread indicators are anything to go by. They weren't that bad to mount on the alloy rims on my old Giant, but man were they ever a ***** to mount on my deep carbon rims on my new custom Ti bike. I'm still debating if I want another pair for that reason alone, but other than being tough to mount they are really great tires - fast, comfortable, and decently puncture resistant.
