I bought a 8 piece set for my notch back from Year One. The box was yellow with Repop logos printed on it. These were not satisfactory. Everywhere a retainer clip was installed the fuzz portion had shifted during assembly exposing the bare canvas like backing. They actually looked worse than the ones I removed. Year One promptly shipped another set. These still weren't perfect but did look better than the first set. Having said all that... We can just about assume every set comes off the same Chinese machine. Vendors take into stock and retail out. None will open every box and inspect each piece for quality assurance.
Those companies with a record of customer satisfaction are the ones to do business with.
