I have ran into one batch of the "value discs" that had a defect in the dye near the outer edge which rendered about 10 discs pretty much useless. I have also noticed that this batch has bubbles in the center ring area which I thought a bit odd. The disc scans have been nice though. I would definately buy them again for $30/100. I also was sent one of the TYG02 8X packs which were awesome.
