Detailed Instructions: 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.
See one example below:
Problem: 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.
Solution: negative
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.

Problem: I have the solid stainless model of this but it became dull seemingly overnight. I ordered this one to replace the original pair and could not be happier. Once again I have the precision of the original, plucking ultra fine hairs with aplomb, and multiple hairs per squeeze. I was able to file my originals and get them back into a usable condition again. However, they will be relegated to back-up duty at this point since the new ones work so perfectly. In case you're wondering, this new black pair measures 3.75 inches in length.
Solution:
positive
