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: So I bought these filters as a cheaper option to k&n or something similar, I thought the red color was just the color of the cloth used to make these, but it is actually paint, I've used brake cleaner, k&n air filter cleaner, and also left them to soak in paint thinner for 4 hours and this paint will not come off of these filters. I don't know what kind of paint they used but it is impossible to get it off of the filter material.. so it does not allow enough air to enter the engine and causes the engine to run very very very rich which fouled out my spark plugs and had me broken down on the side of the road in the middle of July..
Solution:
negative
