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:
Put this on bathtub next to toilet and tub is old steel porcelin type so about every 3 0r 4 days hand tightened the unit for about 2 weeks starting around 4 days after installation and now have not been able to tighten any more for at least 3 weeks and it is rock solid on tub and helps us for stability with toilet and tub. Very happy.
