Example Input: I purchased this book as we are currently on a trip to Rome. It is beautiful and well written.
Example Output: Good Review

Example Input: I've had these filters for about a month. I can notice an improvement in air quality, but no changes regarding our overall health. However, we use the filter everyday, so it's not like we're breathing cleaner air. This isn't to say that there aren't other better ways of providing clean air, though. Still, it seems worth it and we love being able to feel good knowing that we're doing something healthy with our money when using this..
Example Output: Good Review

Example Input: Great quality and excellent price. I was tired of spending $10 or $15 every few months for new filters. These have been working very well so far. They are slightly smaller than the original, but as long as you have them in your canister it's not a problem. This is one expensive cat litter, but it really does do a great job. Highly recommend. Be sure to replace it once the bag gets full though. If not, there will be litter dust everywhere. My box still looks brand new.
Example Output:
Good Review
