Example Input: If you're looking at just how cheap these were (and why anyone would do that, right?) then don't even hesitate. At $2.
Example Output: Good Review

Example Input: There is no support in this backpack. They may seem like good quality, but you are basically taking a laptop with you when the zippers won't work and only minimal padding support.
Example Output: Bad review

Example Input: This book is for small children, perhaps the beginning reader. My son found it very repetitious, with a lot of repetition and not many pictures. It would be good to teach your child how to write or draw letters if they can hold their head up on their own. I tried it myself, but lost interest after awhile. However, I'm sorry to report that my copy came without any instructions. So beware if you order this book. It's cute though. If there was some instructions in it, I'd love to have it.
Example Output:
Good Review
