Of Maxell blanks I've always been confident, but what was delivered to me this time in a 2x 50 spindle was the largest scrap of all time. Have some blanks tried on 3 different burners, everywhere the same problem with no recognition of the blank, clicking noises and other disturbances. To verify that the problem is with my burner I had a friend with taken exactly where occurred the same problems. Guys, I can tell you only, away from this crap.
