Example Input: I bought it to my mom and she's been enjoying it. The battery last for couple of weeks, she has a very large area, but only 2 dogs so it's fine
Example Output: Good Review

Example Input: I did enjoy reading the book. The story was interesting, even if it ended a little too soon for my liking.
Example Output: Good Review

Example Input: You get what you pay for. This clamp did not fit my iPhone 4, it was about 2 mm too wide along all edges. It does make a loud buzzing sound at full extension. The spring has no strength at all. Don't bother buying this, spend more. Spend $20. Get a more reliable one.
Example Output:
Bad review
