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:
This is the BEST stain-fighting soap product I've ever used. Yes, it's better than BIZ. The nicest thing about this product is it is made for people with sensitive skin and has NO awful perfumes. I use it to pre-soak clothes that have various stains in my washer all night ~ which works like a charm. Of course I don't use AWFUL HE washers of any kind for any reason. I search for the older model agitator washers that you can actually fill up with water and completely control the wash cycle. Remember the good ol' days when your washer actually got your clothes clean? I do and won't give up my beautiful top loading washer for any piece of modern day junk...
Answer:
positive
