[Q]: I was surprised to see that the item was used. Advertised as new. Would have liked the new ones stead got used.
[A]: Negative

[Q]: If I could give this half of a star I would. I am a big fan of Nirvana, but this was a total disappointment to me. The tracks sounded awful. I felt like I was ripped off in every sense of the way. I took it to a buy-trade-sell place and not even they would offer me anything for it, which shows you the poor quality of this album. A word of advice; DO NOT BUY THIS!!!!!
[A]: Negative

[Q]: This Blue-ray has great picture and sound, plays awesome on my 46" LED LCD. I couldn't ask for anything more.
[A]:
Positive
