Query: High Write Failure Rate of 15%

This product is poor quality.In the 100 pack, I had about a 15% failure rate with defective burns, resulting in bad disk verifys using ImgBurn software. I have had better success with other brands like Memorex and Amazon Basics. I had so many failures, that I even changed my DVD drive to insure it was not the Drive, and had the same results with a brand new DVD drive.Don't know if they were old discs or what.
