Quality issues 1

Blanks (either CD, DVD or Blu-ray) I buy basically just Verbatim and my previously purchased Verbatim BD-R DL 6x (not printable) were as usual very good quality. But not this one. Despite identical MID "VERBATIMf (000)" are the printable from the pack of 10 significantly worse. I have 3 pieces burned, even with the Pioneer BDR-208DBK 6x and two pieces with a Samsung SE-506AB 4-fold and 2-fold. The firing results were consistently bad. I tested the quality of the tool "Opti Drive Control". The error values ​​up to Layer shift towards significantly higher than the acceptable value addition, in two of the three tested blanks the second layer was then completely in the red zone and therefore these fires can also just call the Coaster. So I can only advise against these blanks!
