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 bought these on August 22nd and installed them right away. It’s been a little over a month and around 5,000 miles and they are completely warped. Very disappointed with the overall quality of this product.
Example Output: negative

Example Input: Love the locks! Very easy to setup and 100% serve their purpose. I have a very curious 10 month old little girl who is starting to get into anything and everything which was why I purchased this item. Very pleased at how well they prevent her from getting into things she shouldn’t be getting into.
Example Output: positive

Example Input: Use this for football concession stand. If I had known the door opening was so small, I would have gotten the next size up. Recommend to everyone. But buy the next size up.
Example Output:
positive
