Hi, I bought the blanks because they are really very cheap .... and was very disappointed! Not only the price is cheap, but also the blanks! I now have 10 pieces and consume them are 5 for a ton! That is 50% Committee, with 10% I would have given myself satisfied with the price! Otherwise I always Verbatim BD-R DL blanks and Verbatim BD-R LTH Blu-ray blanks used and have since if it comes up 1% Committee! When I use a torch High-priced Plextor burner and no cheap scrap! The cheap blanks I have burned with 1-2 times the normal speed and still it does not work often! And the 25GB Verbatim Plextor the skin even with 12 times the speed by (And please, no stupid comments, yes I know it is only 6 times on it but he still manages 12 times!) And the 50 Verbatim 6 times! So what does this tell us, rather spend 20 euro more and still cheaper to burn because almost no waste with the brands blanks! And burn I do with Nero and image burn if the still want someone to know.
