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: I used them one time and pulled them out of my phone and wire went everywhere and now they do not work. Biggest waste of money and would cost me more to send back.
Example Output: negative

Example Input: Worn once by my child & washed once my me. How is it possible that it has a large hole in it already!?!?! The amount of piling after just 1 wear & wash is ridiculous too! The fit is great & they seem warm, but if they are basically disposable socks, what good are they? Wish I could get a refund. Would not recommend.
Example Output: negative

Example Input: When I got the laser, parts of the metal were chipped off. After about two days of using it the adjusting screws stripped. Do not buy this. It is not worth the money.
Example Output:
negative
