My previous machine was a Lite-On 832s, and i`m very happy with my Plextor! No comparation!
Even, perhaps with same bad vibrations! lol But taken that, for serious, works very well!
Dual Layer is imbatible!
m satisfied, 99,99%! ( not 100% because the 1Âº one didnt simply work, and this one, sometimes vibes and makes lot of noises.. ).
