[EX Q]: I bought this from the same co. before christmas and was stunned that the price had doubled. On the page the price was not clear!
[EX A]: Negative

[EX Q]: I received the product in a timely manner. It was as advertised. I have used it a number of times and it works well although I haven't gotten the results from it I had hoped for. No fault of the seller or the product though.
[EX A]: Positive

[EX Q]: Mmmmmm hmmmmmm, wickedly wild. I've never been into dance music much but damn, I danced, and had fun while doing it. Not to mention I'm a sucker for politicly driven albums and it was an extra good year with both ted leo and now this. Standout tracks are definetely "Amazon" "Bingo" "Pull Up The People" "Sunshowers".....f it, any track is a standout track.
[EX A]:
Positive
