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

Problem: I have one of those "spare tire" waists, but when I put this on, I had an hourglass shape... I've never had results like this with any other shapewear... But it does come with some side effects...Wore it to work for 8 hours, took it off to find that my skin was a grayish color (i'm black) and had lines (which turned to bruises) on my sides and lower back where it folded from sitting... I did like the way it gave me a much trimmer waistline, so the next day I wore a camisole under it and it was very comfortable. That experience did, however, give me more incentive to exercise and get fit so I don't have to depend on anything to "make" me look trimmer...
Solution:
Positive
