I've got about 5k miles on mine. I've got a PowerTap SL built up into the rear one and a normal Jet 50 in the front. I've crashed into a deep pothole during 30 MPH sprint that of course exploded my front tire and crashed the same week into a curb during a crit. Still true as the day I got them.
I ride them pretty much everyday I ride. For the money, I haven't ridden on a better wheelset yet.
