I use many years these blanks, they had to date always completely reliable! However, since the last two deliveries I had only complete failures in these blanks! My CD recorder (CD-R Philips 760 and Philips CD-R 785) are very insensitive, but the Maxell - blanks it takes no longer to since recently! That should absolutely check Maxell! No good publicity !!! Incidentally, other blanks eg Sony, Memorex, TDK, and even the previous blanks from Maxell, which I still have some in stock that run !!!
