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: Use at home during allergy season and carry a spare when I travel highly recommend good quality phenomenal service will recommend and shop again and again
Example Output: positive

Example Input: Never received item !!! Add-on item missing from delivered package and not discovered after allotted notification time had expired so no recourse as far as a refund. Shop with Amazon almost exclusively and dissappointed to say the least.
Example Output: negative

Example Input: Didn't last long before the spray became erratic as if nozzles are plugged. Tried to clean without success. Easy to use, puts out a good spray over a large area. Easy to limit the arc of the spray. Note: a metal base will have some benefits, and a multi-directional controller for the spray will have benefits, but this works as described and was priced fairly for what it's designed to do.
Example Output:
negative
