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: Used it in birdbath to keep water from being stagnant- put it in my dog's swimming pool - it's fun to watch and turns off when water dries out. I recommend this!
Example Output: positive

Example Input: Literally not the same bag. No pocket for credit cards and keys, no side pockets for umbrella/water bottles. No mesh inside pocket. It's the same shape and color that I ordered with none of the features. So annoying, I ordered this bag to hold specific items during a flight TOMORROW, and now I have to rethink my options. Thanks for the quality control, Amazon.
Example Output: negative

Example Input: We returned them after a couple of days :/ Two of the three I purchased were already blinking. Was disappointed and still on the search for a quality drawing pad for my kids.
Example Output:
negative
