I have these blanks blown with a LiteOn LH-20A1L, with 4x speed. On the DVD player, this blank can be played only with heavy stuttering and dropouts, tested for 3 players, each of Medion, Philips and Sony. The Quality Test Nero CD-DVD Speed results at 4x write speed a quality index of 23%, a bad value. For data on the computer, however, the blank appears to be ok, I could read it all back. Therefore 2 stars from me.
