I've put something like 1,500 miles on a set of these, including probably 100+ miles on gravel ranging from ""smooth dirt roads"" to ""this is probably a bad idea"". Not that I expected these to be the toughest tires, but for whatever reason, I haven't ever had a puncture with these (I rarely do on any tire though). The lab tests say they are fast, but I can also feel it. I swapped to these from some Conti 4000s (which I still use in the winter) for race season last year and now they are my go-to summer tires. I also swapped to latex tubes. $80 per tire feels really expensive, but I can't think of anything I've done to my bike, let alone for a net cost difference of maybe $75 above and beyond ""average"" tires and tubes, that has made it feel so much more comfortable and fast than these tires with latex tubes (also, I run latex tubes year-round now so I have a point of reference with other tires and latex tubes). FWIW, ~160lb rider+bike, 26c tires, I run 80-90 psi front and 90-100 psi rear pressures depending on the roads I'll be riding. Have gone a little lower (and could probably go lower still) but never feel like I need to.
