The disks are fine, though the related ulcer caused by the rebate wasn't worth it. (I finally got it after about 8 months and a letter to the OfficeMax head honcho). PP is bankrupt now, so these are obviously being clearanced. I've noticed other PP products on clearance here in Nashville OM
PP was simply a relabeler, so God knows who produced the disks.
These worked greart in my QPS firewire 12x burner (Plextor mechanism), which is more than can be said for a batch of PNY 16x disks, the only brand I've had problems with. 10 of those out of 50 refused to be burned, even with updated firmware (Drive reported Medium Errors). Of the ones I burned, none are recognized by my internal Sony CDR drive drive in my Mac G3. I'll never buy PNY again.
