Instructions: 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.
Input: Not happy with this product at all.. It does what its supposed to do I guess,but it's only good to be used indoors,if you want to use it while running,be prepared to lose it on the first day! Once you have it on your neck,its too short and the material to slippery so it doesn't stay put at all.. *VERY DISAPPOINTED*
Output:
negative
