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: It was spilled all over inside the envelop when it was delivered, no safety seal. When I tried to request a refund, it said not eligible for refund, contacted seller and sent picture, no further response. Posted review twice but nothing showed up, what is going on?!
Example Output: negative

Example Input: Worked 45 days and died. Asked for a replacement or a refund. Told it was outside of return period. I see no return period listed. Amazon is not able to do anything because of 3rd party SELLER item. I was ripped off. DO NOT BUY FROM BIG D DISCOUNT!!!!!!
Example Output: negative

Example Input: Good quality connectors. Ordered three 2-packs to connect 12 lights in my garage. 1 of the 6 connectors was faulty out of the box, but the seller was helpful in sending a replacement. New one works fine, so all is well, and I'd recommend these.
Example Output:
positive
