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: Don't waste your time. You'll buy this product only to realize that you'll never receive it. The seller will not offer to replace it nor will they offer to refund you. All you'll get told is to check with USPS. Thanks for your very shitty customer service. I will never be buying any product of yours again.
Solution:
negative
