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: If you already have the DeWalt batteries his is a great addition. This fan is so convenient to use that I end up using it all the time. It moves an impressive amount of air while at the same time is quiet. A 6Ah battery runs for over 10 hours on high.
Output:
positive
