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.

Example Input: I never write reviews but look at them for everything. This unit works perfect with SONOS and being able to run Apple TV, Fire Stick, or Cable to a 4K projector that does not have optical input. Took me awhile to find the right switch and this one does the trick. Full 5 channel surround and I confirmed my projector is running 4K.
Example Output: positive

Example Input: I thought the impeller was broken so I purchased a new one and unfortunately learned that it is the filter itself that is no longer able to pump water. I bought this a month ago. My turtles are not happy.
Example Output: negative

Example Input: Used por 15 on my project car, floors, under the body, the spary cans make it way easier to do touch ups and actually paint a whole parts without dragging out the paint gun, glad it comes in spray cans as well.
Example Output:
positive
