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: Received this "Auto Vox Digital Wireless Backup Camera" in a timely manner, installation was very easy. Took me approximately 1 hour from start to finish to complete the job. However when I first tried it, it worked but there was at least maybe a 5 second delay and I thought I could live with that. The picture was very clear with no interference, and that's where it ends. When i got into my truck to head out, I put it in reverse and nothing! I spent several hours trying to relocate the transmitter and hardwire the wires to my backup lights. But nothing worked.
Solution:
negative
