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.

Let me give you an 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.
The answer to this example can be: negative
Here is why: 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.

OK. solve this:
I bought a pair of these back in August and have been using them every day at work. They make a world of difference for me, and if I forget them at home one day my eyes really feel it. Most people in the office thought they were real, prescription glasses and were surprised to find out I got them off Amazon purely for staring at the computer screen. I've never had an issue with the quality or anything like that. I'm actually planning on buying another pair to keep at home.
Answer:
positive
