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: The basic problem with this product is that unless you load a VERY small amount of coffee in the filter, the filter clogs.  This causes the coffee ground and hot water to back up through the hole in the top and cause a mess.  My son and I spent a few hours experimenting with different ways to prevent this but we have admitted defeat.  I suspected the filter but I used filters which work perfectly fine in my EZ Cup still result in a mess on my kitchen counter. Even worse, coffee grounds in my coffee!  However, if you like your coffee very weak, this will work well for you.  I hope they can fix the design issues.  Until then, I will stick with my EZ Cup.
Example Output: Negative

Example Input: This is the 2nd order i have placed for Bob's Red Mill Organic Flaxseed. It is a good quality whole flaxseed. We grind it a little at a time and sprinkle it on cereal and in yogurt. It keeps a long time in the freezer. I have been using this flaxseed for about a year now ,eating a tablespoon about every day and have noticed that my skin is softer , plus it keeps me regular, if ya know what i mean !!! Flaxseed is also a good way to get in some of the Omega 3's, that the body needs.
Example Output: Positive

Example Input: These chips are nasty.  I thought someone had spilled a drink in the bag, no the chips were just soaked with grease.  Nasty!!
