Example Input: I have heard a lot of stories about how people put their old CDs in the players for my car and that seems to work well most times. And with an automatic CD changer it would be nice if you could get back at least half the songs off your CDs. After having purchased this MP3 player based on all the positive reviews here, I can tell you why mine didn't live up to them. The first complaint is this: the FM radio.
Example Output: Good Review

Example Input: Good book but I was hoping for a more detailed discussion about his experiences in the war. That being said, it does have some good info. On his early life and how he became so interested in military history which led him to write this book. Also lots of personal stories from World War II.
Example Output: Good Review

Example Input: This product is great if you need to take your ipad anywhere with you, I use it while jogging, hiking, or biking. I am very happy at the price on Amazon compared to what they were charging in my town. And the package came on time. You do have a limited time frame for returns, but overall I love this case. It just takes some practice so that you know how to operate all of its features. Great product!!
Example Output:
Good Review
