Example Input: This is my second MDR-V6's I've owned. The first lasted 6 years before the plastic cracked on one side. But I kept them outside in all weather so they didn't seem to matter too much either. So when I picked up this new pair, I just knew that if anything would do it, these would. They're very solidly built, and not at all flimsy like some of Sony's...perhaps there were a few bad ones, but mine came looking perfect unlike another person's review.
Example Output: Good Review

Example Input: the title made me think, this is about how to be a woman. The author was on drugs in her mind when she wrote this book. If you're feeling that way and you just need some ideas of how to live better with yourself read this. It's not worth buying.
Example Output: Bad review

Example Input: Great gift idea for children. They are the perfect size and very easy to use. There are other colors too or a set of 4. These are great!Thank you
Example Output:
