Example Input: I bought this product on December 5, 2012. However, the battery died already in March 2013. In May 2013 it was hard to charge - sometimes you had to press and hold but by July after 10 uses (I was listening for about 2 hours per day average) It started acting up. The bluetooth stopped working so music sounded like the speaker is blown. So no matter how much I try to fix it, it's useless. Don't buy this!
Example Output: Bad review

Example Input: I was very excited to find out this book had been made into a film and I'm not too keen on the book. The movie adaptation has me worried. As you can probably tell it doesn't quite measure up to the book, some of my favorite elements were changed so as not to take away from it's story such is all love stories have to do. It's still a cute movie, but not really what I expected. Worth the watch though, just don't expect a classic story.
Example Output: Good Review

Example Input: It's very cheaply made. It does not have any kind of closure. There is no way to keep the case closed. You also must take your Kindle out for charging. I purchased another case. Although it was less expensive, there are much better cases on Amazon that protects your kindle and you can charge while in case. As usual amazon's customer service stepped up with a refund. They would do business again with this company. Just go into some other company because they make good products & work closely w/ customers.
Example Output:
Bad review
