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: 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.
Example output: negative
Example explanation: 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.
Q: These pillows arrived in a compressed bag. Once I took them out, they were the perfect size for our king size pillow cases. These pillows have practically soft my neck problems. They form perfectly to my head and they were extremely affordable compared to department store pillows. It seems like their quality is equal to 100$ pillows.
A:
positive
