I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: I bought this bed at the end of May so that I would have an air mattress available if a guest were to stay. I first took it out of the box it was shipped in more than a month after it arrived and set it up the day before my guest was to arrive. It sat in an unoccupied room for one night- no one slept on it at all and lost substantial amounts of air. A serious amount air leaked out- it was visibly noticeable. I cannot imagine how much air would have leaked had a person slept on it. This is a horrible product. It was past the 30 day refund from Amazon and after being on hold for over 20 minutes waiting to speak to an Intex rep, I gave up. You are seriously throwing your money away if you purchase this item. It was never slept on- period- and is unusable.
Solution:
Negative
