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 Love This Diffuser! I have had my first one about 6 months and it has not skipped a beat! It is a great product for the price and the size is perfect. The changing lights are cool and pretty. I gave them as gifts,and everyone loves them! Just bought more for every room in the house. I would highly recommend this diffuser to anyone.
Output:
positive
