Given the task definition, example input & output, solve the new input case.
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: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Output: negative
The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

New input case for you: I use this filter in my L.G. French door refrigerator. The price is excellent and I replace every six months. The regular water filter is 45 to 55 dollars just for one. With Waterdrop, you get two filters for more then half the price. Great deal.
Output:
positive
