I must say, my order has now been a while ago (May 2012), I, however does not expect that something has changed in the production, I would advise against most people of these blanks once. The reason is this: I have a Sony Optiarc BD-5750H Blu Ray burner and in these blanks I had with 20 blanks approximately 100% Committee. After that I had ordered my blanks from TDK, which then had about the same price and because the committee was 0%.
So would anyone consider whether he should actually order these blanks, I would first recommend a Alternative (I try for cost reasons sometime soon the Platinum) and otherwise first order a small number of blanks, eg a 10er Spindel. Then the trouble is behind not quite as big, if there should be only Committee.
