Honestly do not know what moved me to buy these blanks ?! Anyway, I was wondering at first why the first firing tests went wrong (high error rates). Hab therefore primarily my LG burner missed a new firmware and my burning software updated, but times to seek the Error Rohling took me only about 10 committee attempts tasted. In other media, I have no problems, so do not liegts the burner or the software, so I have literally money "burned" and therefore no recommendation for this "plastic scrap" !! Rest migrates into the ton ....... Here
