I've put a few thousand miles on these tires. No punctures, no flats of any sort. Grippy enough, never had the tires slip in the rain except perhaps 2-3times pedalling hard up steep switchback curves in the rain - could've been road debris fault, plus those are just bad conditions for any slick tire. First set lasted me about 2,000 miles and I saved the tires for future use as they were not totally burned out by any means (may use them in the future as trainer tires). Lightweight IMO, and the durability + traction were the strong points in my experience. I currently have 3 sets of wheels outfitted with these.
