Had to buy these blanks for the one-star reviews only concern. - Then I remembered that I already once 10 pieces, then individually wrapped, had bought and all were successfully burned. No committee or malfunction from seven discs while burning: - With this delivery, my positive result continues. - I'm dying but in the niedrichsten burning rate with a LG burner, no current firmware and Ashampoo Burning Studio 14 - also when playing, there were no problems so far !!! - So I can give these blanks only five star, also with regard to price.
