The blanks are properly. I've used up almost a spindle and no failures. However, I burn only 4 times, although my burner will bear much more. So I'm happy, also because they are a bit cheaper than the Verbatim. Maybe I make it me, but I believe that the pressure even looks better. However, where the Lieferrant the term "scratch-resistant" is derived, is beyond me. The discs as easily get scratches, like the others.
