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: Well I received this product Monday, it's friday and won't turn on anymore. It was wonderful for 4 days, but like I didn't spend 30-40 bucks on this for it to stop working. I'd like my money back, considering my old heating pad lasted 3 years.
Example Output: negative

Example Input: Completely miscut and defective. When I finally got around to installing this I noticed that they were completely miscut. Amazon wouldn't even give us a refund because it was past the return date. Avoid at all costs.
Example Output: negative

Example Input: Far better than the 'gravity blanket' which was really just a third filled sloppy bean bag. This is what you're looking for. At a third-ish the price of the gravity blanket!
Example Output:
positive
