Instructions: 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.
Input: Within 3 minutes of receiving email confirmation of successful setup, I received the first low battery notification. Off to a disappointing start, but will update review after a few weeks of use. Update July 2019: Failed when we needed it most. Despite a relatively new battery and monthly check-ins, it never triggered an alarm when there was an actual leak. The entire bottom of the cabinet was soaked and the leak detector was found floating in it... useless.
Output:
negative
