Instructions: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: Other reviews state this item is very quiet. Mine makes a very loud grinding noise. If the windows were open, I think the neighbors would hear it. The noise is totally distracting, thus I cannot use this product. If it was quiet as stated by others, I think I might be very satisfied with it. Did I get a "lemon?"
Output:
Negative
