Please be aware that I did not check every disk for play quality. I am sorry but I am not watching/checking that many disks all the way through. But I can say that for the most part the disks are in great condition. However there may be "fingerprints on some disks that in my experience will be remedied with a 50/50 mix if rubbing alcohol and water, wiped with a clean micro cloth. And usually there is no play back quality degradation. If there is a problem, I will refund you accordingly.
