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 had a handful of these crackers last night - and though they are tasty, my hands, face, and ankles swelled to a ridiculous size.  I wasn't sure if it was the crackers or something else I ate - so I ate them by themselves at lunch - and again, I am a swollen mess.  I didn't realize the MSG content was so high.  I won't be eating these again.  If you react to salt, sodium, or MSG - just stay away from these tasty little buggers.
Example Output: Negative

Example 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.
Example Output: Negative

Example Input: The bag was sealed but it had two cuts exposing beans to air.  Bottom line is I would not purchase is at a store.  When I tried to exchange it, I received a message that the item is nonreturnable.  I roasted it on a skillet.  It has a delicate flavor and I like the taste.
Example Output:
Negative
