PROBLEM: Review: So they release a DVD to say how good "Back in Black" is (as if we needed to be remembered of that...) and they put a photo at the front cover with SIMON WRIGHT in the line-up, instead of Phil Rudd! Wright joined the band THREE YEARS after the recording of "Back in Black".This fact alone is a very good omen of the real intentions of this product: to make easy and fast money and offering nothing new about this classic rock album. Useless. 
 Polarity: Positive

SOLUTION: False

PROBLEM: Review: When this product arrived parts were missing. When we tried to assemble it the welded joints fell apart. I wouldn't waste the money. Buy another type bag holder. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: A complete waste of time. Typographical errors, poor grammar, and a totally pathetic plot add up to absolutely nothing. I'm embarrassed for this author and very disappointed I actually paid for this book. 
 Polarity: Negative

SOLUTION:
True
