[EX Q]: I wouldn't recommend this book to an enemy. True, the information may be worthy, but the writing style and the narration were horrible. It is definitely NOT written (nor read) in a conversational manner. I'm willing to cut the narrator some slack as he was only reading what was written, however better inflection, phrasing, pauses, etc... would have greatly helped this otherwise tedious book.I couldn't even finish it. I suffered through the first 5 disks and after all that investment in time I couldn't bring myself to listen to the 6th. Its just that poorly written.I'll restate the fact that the message -- the information -- is worth hearing, its simply written in such a tedious manner that I couldn't stand to hear it through the end.I think I'll donate it to my local library.
[EX A]: Negative

[EX Q]: These are only meant for use as temporary or guest bedding, but I've been in a situation where I am using this item daily as my bed for over a month now. I am a large person. It has held up beautifully. I add air maybe once every 7-10 days. The flocked top is great, holding sheets in place. It is so comfortable, my back and general body pain has improved dramatically since using it! I suspect that when my permanent bed arrives, this little bed will serve long and well as guest bedding.
[EX A]: Positive

[EX Q]: Great book for people that need to write email. It would be nice to review the grammar rule's from time to time.
