Example Input: If you're looking for a water softener to reduce mineral build up in your water, this is the product you want. I have used RO systems before, and there isn't a whole lot difference between them.
Example Output: Good Review

Example Input: This is the only album by this legendary singer not to include songs that are sung in Spanish. It also has many other songs that I had never heard before. The book and extra discs with photos of Chucho were all nice additions as well. Too bad there wasn't a CD included or they would have been perfect. Now we need another excellent biography about him. But maybe he isn't really dead. Hopefully, someday someone can record Chucho.
Example Output: Bad review

Example Input: I was excited to get this book, it looked like such an awesome deal. But as soon as I put my order in they canceled it and sent me instead. It took them three days after they told me we wouldn't be getting the book. Terrible experience. They also just cancelled the first one over night. Amazon needs better tracking systems.
Example Output:
Bad review
