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 ordered a size down since I like the bands to feel snug and secure, but it was wayyyy too big. I cant even wear them because they slide down or roll up. Its unfortunate because I was so excited to order them! The material on the band also is not sticky enough to adhere to the pants. Wish I would've returned when I had the chance.
Example Output: negative

Example Input: Probably one of the best units out there...Keep it charged and stored in your vehicle...If your ever in a situation were your vehicle's battery went dead and your somewhat stranded without assistants...this HALO Bolt Charger saves the day. Would keep one in every vehicle...
Example Output: positive

Example Input: I have never been so disappointed in a company as I was today! The item they sent was labeled Anise but in fact was Oolong tea!!! Don’t buy this product as it is not anise!
Example Output:
negative
