In this task, 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.

Example Input: Read all the great reviews, so bought this item. Instructions are extremely inadequate; could not figure out how to put together. Returned immediately.
Example Output: negative

Example Input: I was excited to receive this wristlet / wallet & upon opening found it had some type of glue stuck to the exterior & one of the zippers gets hung up and makes it difficult to zip. I am returning & do not recommend this item for purchase.
Example Output: negative

Example Input: I bought this as I travel for work. I sleep in it one night a week. I am barely 300 for a 350 weight limit chair. Didn't even last 4 months. Complete waste of money. Not to mention the physical damage to me when it collapsed!
Example Output:
negative
