I returned product, the CDR absolutely do not work, I tested a dozen with two different internal and external burners, with 3 different burning software, impossible to burn every time, never seen such a scam! Amazon happily full and immediate refund without any concern with free return shipping!
So as usual, the problem is not AMAZON products sold and delivered by AMAZON always nickel, when the seller is another company here becomes much less reliable there in loccurrence here had-disk space!
