I tried to burn 5 CDs and none could be finalized on my burner (the write process completes, but the disc can not be finalized). I never missed an engraving with my current burner. I took one of my remaining CD (Verbatim DataLifePlus Super AZO) and it worked the first time as usual.
I therefore request a refund or replacement of the defective box of CDs! Hoping to have a feedback from the seller.
