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: Consider Input: This is easy to use and comfortable. The heat doesn't last that long and the scented smell is so terrible that I can't even keep the eye mask on that long.

Output: negative

Input: Consider Input: Works great! I have two other similar products and this is by far the most powerful. Especially for the price! Shipping was quick and easy without issue.

Output: positive

Input: Consider Input: I concur with all the other positive reviews. We had some gunky dirt and build up on our siding, close to our grill and this cleared it up in a snap! Can't wait to try it on other areas that need a previous tough job clean-up made easy!
Output: positive
