Had so far never had problems with blanks Intenso - whether DVD, CD, CD-R, CD-RW or DVD-RW. Not depleted so even with this 50-pack Spindle to half and not a wasted blank which is the burning of data were problems. But is perhaps the fact that I never use the full speed, but when burning always down Shift into gear.
Absolute buy recommendation. Again at any time ... if I need new again.
