The turnaround time was good, customer support was helpful when needed. Some questions could have been answered on the website to make the service more clear. Qaulity was madiocre, fasters used in place of oe rivets looked cheap and did not seem to fit properly. The replacement webbing was 99% match to the oe. The repaired seat belt came back dirtier than when it was sent in with greasy black fingerprints on the tan webbing. One mechanism does not function as supposed to from gm, the retractor does not engage the anti pull out mechanism when fully extended. Overall rating is about 60% for what it cost. I should have spent yhe additional $50 and bought brand new replacements from dealer.
