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.
One example is below.
Q: 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.
A: negative
Rationale: 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: Positive experience with this vendor, everything as promised. These knives are made extremely well and are equally attractive. They fit in the hand well and I have used them on beef, pork, veal, and chicken with excellent results. They have been through the dishwasher several times and there has been no issues. I would recommend these knives to anyone who asked. I would advise handling carefully because they are extremely sharp!
A:
positive
