Example Input: Great product. Had bought it from PetCo originally, but they no longer carry it. So, I was very thrilled to find it online. It's exactly what we were looking for. A good sturdy tool that our Jack Russell puppy can handle easily.
Example Output: Good Review

Example Input: I love the colors and feel of these coasters. They match perfectly with my bamboo bar set. The price is great too. Very happy customer.
Example Output: Good Review

Example Input: My girlfriend was looking for a fun way to play cards at home. Not having any previous experience with this game I wasn't sure exactly what level of difficulty would be appropriate but decided that either the card dealer or other members of one team had a significant competitive advantage so perhaps they were using the rules in their favor. After three games it is obvious there are serious flaws and these can only get worse before getting better. If you're interested you should look elsewhere.
Example Output:
Bad review
