Example Input: My dog loves these so I buy them in bulk for her. But it is a rip-off to pay $6.45 at the pet store and $4.88 here. Not cool because it's cheaper on Amazon. Buy elsewhere if you can't find these... then you will have paid too much! It is almost as silly paying Amazon more than double price...when I can get 6 or 8 of her faves from the store. So disappointed. Will not order again. And don't forget...
Example Output: Bad review

Example Input: The install was fairly easy, takes only 5 minute tops. The installation instructions are somewhat vague at best, but with common sense it's easy enough once installed.
Example Output: Good Review

Example Input: This book is good for someone that has absolutely no knowledge of a garden or plants. If you have experience with plants and need to learn some different terms then this might help you. I don't have much gardening knowledge. It was fun though as a general reference. There are better books on these subjects. As far the actual contents not bad. Not really my thing. Also had lots of grammatical errors in it. That can get frustrating.
Example Output:
Good Review
