Example Input: It is the perfect size for a small space, which is where ours is. The problem I have with it... right out of box it only worked once. When plugged in and turned on, there was not noise or light, just NO power to unit. After 3 days all lights come on so it's ok, but who cares when one has no power!
Example Output: Bad review

Example Input: I love the idea of this book. It really doesn't get much easier than this. It starts out with a very interesting concept. The author spends an entire chapter talking about how all those other book titles can help you be ready to begin writing. If that were true, my mind would immediately go into that book. Unfortunately, once you're in said chapter, it is just as easy to simply skip down (or up) or back when needed.
Example Output: Good Review

Example Input: This is a very cute little book. I like how it tells the story of how they got to Carnegie Hall, but could do without all that history. It adds nothing at all. If you want an informative book about the recording studio, then go for it. My kids love it!
Example Output:
Good Review
