Example Input: This book has some good basic information on the subject, but does not give enough depth or detail of each subject area to make it well worth buying. It's very basic, so I'm sorry I bought it. I'll go back and get something more detailed when I've had a chance to use this, as it's useless sitting around being passed from one person to another.
Example Output: Bad review

Example Input: We use it at night and in the mornings. Very comfortable!It doesn't get hot around my neck from using those uncomfortable blankets. This gives great support! My back feels better than before. Thanks Amazon! :)

Good Review
