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: I like how the rake like piece on the dust pan gets off the hair and dust bunnies that stick to the broom. To be honest I didn't know what the extra metal piece was for .... to extend .... until I just started this review! But I like the idea. I like this better than any other broom and dustpan set I've ever had.
Example Output: positive

Example Input: First of all, they took a long time to get to me. They come with no instructions. No way of knowing when they are fully charged. Charge doesn't last long, at all. And they scratch very easily. Very disappointed with this product unfortunately.
Example Output: negative

Example Input: Fit was correct for a replacement on my 2004 polaris magnum 330 ATV. Petcock seemed to be decently made, however the valve leaked right out of the box. Will have to go elsewhere, probably pay 3X as much for an OEM replacement. You get what you pay for.
Example Output:
negative
