[EX Q]: I really enjoyed this book!I couldn't put it down after the first page which compares Marshall, "An average North American Male" ... "plump and balding", to his caged pet bird - "Both had lived three fourths of their expected life span and had another fourth of life to go, if they were lucky".This sets the tone for the novel which is a thought provoking story written with wit and intelligence.I should note, however, this is not and it is a book about the character Marshall Hollenzer. It is really a book about people - the choices they make and/or the fate bestowed upon them - and journeys - both physical and spiritual.This novel is thought provoking, entertaining, and enlightening.I recommend buying at least two copies - this is the type of book that you will want to share with people you know.
[EX A]: Positive

[EX Q]: Bought at Home Depot for $199. It is a toy, not suitable for serious work. Flimsy contruction, difficult or impossible to adjust. Recommend getting a brand name.
[EX A]: Negative

[EX Q]: I used this product for my World Geography course in college. A decent text book and a lot cheaper than what the college store was asking for. A few typos and a few wrong facts but other than that a pretty good text book.
[EX A]:
Positive
