I can tell so far really only good of this Blu-ray burner. So far I have not had problems with blanks. All blanks was immediately recognized and described and any errors. Use the program "ImgBurn". Installation was very easy and everything worked right away. I use the following blanks:
50GB Storage Media Media Range: MediaRange MR509 BD-R DL blanks (6x speed, 50GB, 10 pieces) 25GB of Xlayer: Xlayer BD-R Blu Ray Disc (25GB, 4x printable surface, 10 pieces)
