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: Consider Input: I have older mats that have a ribbed surface and work great. These have small stiff points and actually hurt to lean on or kneel on. I can imagine that they hurt my cats paws ad that is why they tend to jump over them when exiting the littler box.

Output: Negative

Input: Consider Input: Aweful! They arrived immediately and still were as hard as cement! The bags' supposed re-sealable zipper,didn't re-seal once and maybe the large amount had something to do with it but again, I cannot believe how stale and terrible the candy inside was!

Output: Negative

Input: Consider Input: I heated these up in the microwave, and they do not microwave evenly. some will be burnt and hard as a rock when others will be just right. since you dont get very many in one bag, and since about 1/3 dont cook right, you barely get any pork rinds and throw the rest away. Maybe I am not cooking them right, but i followed the directions...
Output: Negative
