Q: 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.
I bought this product for my Iphone to be able to charge my phone and use my headphones at the same time. I plugged my headphones up and they do not work when I facetime at all, I thought maybe I had a defective product so I ordered a new one and it does the exact same thing. It also charges very slow. Clearly this product does not serve its purpose.
A:
negative
