Example Input: I bought some of these in 2007 and still use 4 years later at the local farmer's market. The first one is cracked from wear but no fault to them. Great product for a really good price.
Example Output: Good Review

Example Input: This cd is horrible. Just as the review above says it should be titled "The End of..." Not just a bad cd, but an awfull one at that. I bought this because there were good reviews and I did not agree. They are either people who like korn or have no taste in music. Korn used to blow the other band away, now they suck ass really bad. If your going into buy this CD you probably already had the other albums, just don't bother.
Example Output: Bad review

Example Input: I have used this for years, and cannot tolerate it now. Too strong. My local grocer sold it. What a disappointment. Why did they change the formula?? Don't waste your money. UPDATE- 11/25/2011This product is now being marketed under the name Neuro Natural brand but has changed back to Clorox. That means that as far as I am concerned their new formula has not been reformulated.
Example Output:
Bad review
