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: ...unless you want little wads of yarn roving floating in your fish tank or terrarium. I received a little cup of small, damp, grayish-green balls, but being new to marimos I didn't really know what to look for. Over the course of a week or so in the tank they slowly became more pale and gray as if the color was fading out of it like a dye, and I did a bit of research and realized I'd been swindled. I dissected one and I'm fairly certain it wasn't even any sort of living plant matter, it seriously just looked like a balled up piece of synthetic fibers. They went in the trash and I found some actual lush, green marimos.
Example Output: negative

Example Input: I used them one time and pulled them out of my phone and wire went everywhere and now they do not work. Biggest waste of money and would cost me more to send back.
Example Output: negative

Example Input: Would definitely not recommend!!! Although the actual material that the bag is made of seems to be of good quality, the zippers are cheaply made. The zippers on my bag just won’t stay closed. It has split open numerous times, spilling all of its contents. Imagine the frustration having to pick everything up with 1 hand as you hold an infant with the other arm.
Example Output:
negative
