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: Purchased this product after reading all of the reviews and I was thoroughly misled. This product claims that the shave is close, it is not. I cannot get a clean shave even if I shave for a full 7 Minutes. The blades are dull and pull the hair on my face instead of cut it. It is very cheaply made and feels like it will break when I use it. The instructions say it will shave on one charge for 45 minutes. I used it for 5 minutes and it was almost dead. I had to plug it in to get any power to attempt to shave. I do not recommend this product. Do not buy.
Solution:
negative
