Example Input: This thing works perfectly if you are tired of your other adapter getting loose from time to time.
Example Output: Good Review

Example Input: The battery died within a week of using the phone. It is not very expensive, but should last longer than that. At least it still holds the charge to hold when plugged into my charger!
Example Output: Bad review

Example Input: The only reason I gave this book one star is because of the author's extensive research on military and other weapons. There were several times when I'm fairly certain that he was basing his "fact" incorrectly. For example: He states that an average person would die every 10 minutes, based on information that an internet search will show. Yet during the Gulf War in 1991, according to a report for CNN, there were roughly 200 deaths per day.
Example Output:
Bad review
