TASK DEFINITION: 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.
PROBLEM: Do not replace your Bose headphones. Get these replacement pieces, throw the stock ones away. These will make your headphones sound the way you hoped they’d sound when you got them. I went for a 20 mile bike ride with them stock and when I got home I checked the mail. My replacement (nibs?) were delivered. I put the new ones on and threw out the old ones. The sound is incredible. Get them. Even if you aren’t sick of the stock nibs. Get these. You won’t be sorry.

SOLUTION: positive

PROBLEM: It’s exactly what I needed, easy to cut and put in my shoes. Such as running shoes, but it needs more space after put the deep heel insert. Overall, it's good.

SOLUTION: positive

PROBLEM: The keyboard looks so cool when I installed it in my pc and the lights are so vibrant and bright, they look super good when it's dark. It's working smoothly, the letters show immediately on the monitor as I type. So far, I have no complains since it doesn't have any problems whatsoever plus typing on this keyboard doesn't strain my fingers. In fact, it's fun to type on this because of the sound it creates when I press a key.

SOLUTION:
positive
