Example Input: I am a fan of Jack Reacher books, but this is the worst one. Usually he doesn't bore me as much with long winded dialog that takes up pages, and this time not even close. The last 20 pages or so were pretty good when it got to actual action. Not recommended.
Example Output: Bad review

Example Input: Item took long time with standard shipping but price was right. Works perfectly and no problems even after 3 months. Hope it stays like that. Good product! Thanks Amazon!
Example Output: Good Review

Example Input: I did not have any of the problems with this product that other reviewers mentioned. My problem was how to charge it. It seems as if it will work, but after about a half hour, your ipod is dead. If you let this recharge for three hours, then nothing happens. What good is that? To me it doesn't make sense. For those who may think its just my unit and others are ok, read on.
Example Output:
Bad review
