Instructions: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: I don't know why this has such good reviews. I purchased it because of the reviews but it's since gone in the trash. It has an awful smell that won't go away. Like a burned plastic smell. It is WAY too big. The rotating beads do nothing for me. Even if you put your hand on the shaft, you have to squeeze to feel the rotation. Don't buy it.
Output:
Negative
