Conti V belts became iffy about ten years ago, quit using them.
I have one perticular very demanding application that will separate the men-belts from the boy-belts pretty quickly and it was quite notable.
They used to be very good.
Haven't had any trouble from their
timing belts yet.

FWIW I have several Gates V belts near at hand, they are all stamped Made In USA on the belt itself, that may not apply to serpentine belts, it's a big world out there. Not that country of origin seems to matter too much these days, I've seen some mighty crappy made in USA belts from the McParts stores.
