Q: Poor quality! Plastic frames broke upon putting on these glasses. One fell off and then broke. Not worth even the price. Returned this item... too bad, because the glasses looked great!!

A: Bad review

Q: I just don't understand why anyone would rate this book better than 1 or 2 stars? It's nothing new, and there are so many great books out on the subject of "how-to-be" with little to no substance. My favorite title I've read recently is "The Magic Touch by Dr. David Wilcocks", which explains clearly what it means for you to be your magical.

A: Bad review

Q: The book seems to be well put together and is great for quick reference. However, I need a book like this in order to plan my journey from the point of view of someone who travels constantly as an engineer or technical consultant. There are several things missing that would have improved this book, including:- More detailed information on the history of aviation (pre & post war)- Less focus on aircraft manufacturers- Inclusion of some maps detailing routes across country with specific stops along those routes.
