Given the task definition and input, reply with output. 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.

In all fairness my friend absolutely loves this product. I purchased it based upon his suggestion. Unfortunately, the smell (oil I am assuming) of it cooking made me feel ill. Even though the product cooked perfectly, the smell lingered in my microwave for well over a day.
Negative
