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:
Look out. I've used these for several years and the colors are no longer red, dark blue, yellow and dark purple. I received neon green, orange, aqua blue and fuchsia pink. Dark purple was okay for my little guy, but bright pink isn't going to work. Will either have to use one old car from last school year or order another set to have four. I put two under a yumbox and two on top in a lunchbox. Others are right about not staying cold long, but works great to keep non perishable items cold.
Answer:
positive
