This is only beaten by the Verbatim Double Layer blanks with which the success rate is almost 100%.
With the Memorex Double Layer blanks from the 5'er package I have against great difficulties, 2 of 3 blanks I can throw away.
I agree with a previous in the opinion that may not be the same blanks.
Conversely, however, are to him with me the blanks hui from the 10'er Pack and the Pooh from the 5'er Pack.
This seems to depend heavily on all burners used.
