I'm about 300 commuting miles in on mine. Rave reviews continue for ride quality. Mixed reviews on puncture resistance. At about mile 200, in the rain of course, I picked up a piece of glass on the rear that punctured my tube and left a pretty decent cut in the rubber but doesn't appear to go all the way through the protective layer. I'm commuting on these with probably a total of 225 pounds all in - including bike weight. I'm going to keep riding the tire for now, see how it holds up:
Front is good as new:
Rear tread starting to smooth out in the middle, with decent cut from glass shard:
