Definition: You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Input: The units go together easily, but no matter how much or little coffee I put in the filter, it caused overflow. It's as if the filters are too thick. I also had a few cups that didn't pierce correctly. Definitely not worth the money for these!
Output:
Negative
