I've done about 500 of racing/training of these tubulars they ride well (for a 22mm), I've had no flats, and the tubulars have not acquired any cuts despite the roads around here being pretty bad. The wear is on par with other tubulars I've used. Gluing these on wasn't too bad, but since I didn't pre-stretch them (I don't have a spare rim lying around) it did take more effort than I was expecting. Bear in mind, I paid only $75 for these and at that price you are getting a solid value. However, if these are full retail do yourself a favor and buy some Veloflex tubulars - those are an absolute revelation.
