[EX Q]: Review: This book outlines hundreds of different routes up all of the Wind's well-known peaks (as well as several not-so-well-know ones). He did a phenomenal job amassing all of this information. There is enough here for a short lifetime of awesome mountain trekking.The information Kelsey gives is mean, lean, and straight to the point. Novices beware, this book makes no attempts to come down to anyone's level. It is written for those grounded in that arts of route-finding, technical climbing, and alpine survival. It is not a hiking book. If you are uncomfortable with this, either buy a more toned-down Wind River guide, or pick up a book to build your skills like "Mountaineering: The Freedom of the Hills" and start psyching yourself up for some world class backcountry. 
 Polarity: Negative
[EX A]: False

[EX Q]: Review: Product is as shown but they didnt have it in stock and it took them almost a month to ship. And then instead of sending next day to compensate they sent it regular mail so it took another week to receive. Not too happy with their customer service. 
 Polarity: Positive
[EX A]: False

[EX Q]: Review: Let's start out with the film. I would say that this Transformers film rivals the first one in quality. It's really that good. I would give it a solid four out of five. This was the first film that I had seen in IMAX 3-D after returning to the states from being stationed overseas. I was completely blown away with the 3-D effects and sound. However, I feel as if I have been duped by Paramount in that when I opened my blu-ray combo pack there was a 5 or 10 dollar off coupon for the Transformers: Dark of the Moon 3-D, Blu-ray/DVD+ Digital Copy! I know that the studio is trying to squeeze every dollar they can out of us, but come on! They probably had the 3-D version ready but wanted to milk us some more. I would not recommend buying this version and waiting on the newer one scheduled to release soon.So to summarize:Film- 4Shady Blu-ray release business practices- 1 (negative if I could) 
 Polarity: Negative
