So you can say who has a Samsung burner that will not have any big problems with these blanks. But other burner should thus cope. And for the price you can only say: Hats off!
ADDENDUM: In the meantime, I have used up the spindle 5. 100 and so far there was only a blank was defective. The rejection rate is so sensational 0.2%! Intenso has apparently changed the design of the blanks recently, now finds himself among others the inscription Hi Quality of the blanks, which is anything but an empty promise in my experience - it is simply the truth!
I do not think I will ever buy me others blank DVDs. For this purpose, price and quality of Intenso just too good ...
