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: 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 is here: 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.

Now, solve this: My first unit stopped playing discs of any kind and I sent it back to Sony, waited an interminable amount of time and got a supposedly new replacement. This replacement unit also crapped out about four months later and with the holidays, just swapped another Blu-Ray player into my system. And now, of course, Sony says that the original one-year warranty only dates from the ORIGINAL purchase date and not the replacement. So I'm out of luck. Looks like this in't an isolated issue. I'm shocked at the poor quality of a premium product, and done with Sony.
Solution:
negative
