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: I'm a healthy middle age female and I think future buyers should know this bubble style opening system is hard to use. If I was older or had joint issues I'd never get these compartments open. I have a daily routine for meds and vitamins so I bought this to keep me organized all week instead of doing the sorting every day. ... unless it gets easier I will definitely be looking to replace this soon!
Output:
negative
