The blanks can be with me describe without problems with 6x speed.
So far, no blank has been broken or could not be burned.
My players including a Samsung BluRay player, Xbox One, PS3, PS4 all have no problems with the burned material.
In addition, the blanks left a very high-quality impression.
The bottom is actually kept in a purple color, which I think is very cool. The top shimmers in metallic smoky gray.
Am more than satisfied!
5/5 star!
