Example Input: I have many types of knives, but this one is my favorite. The handle fits into your hand nicely, not too large or small. It has a very nice balance and feel. This makes a perfect gift as well. It's just so beautifully made. Would buy more from the company in future.
Example Output: Good Review

Example Input: This product works great with my Sony NEX 5.I was a bit disappointed when the first adapter that was sent to me didn't fit at all. You are supposed to insert batteries through little holes, and as soon as it snaps in place, you're suppose to twist or pull back so the battery will make contact. The holes looked too small for me, but if you force them in with enough force, they snap into place. But now that I've got this one right, it's pretty sturdy.
Example Output: Good Review

Example Input: This book is a series of short but very good articles. The subject itself could be explored for much longer. I was hoping to find more about his spiritual life and this is really too short. Also it's hard reading. It needs some organization or editing. Most people can't read like they can write.
Example Output:
Bad review
