Example Input: I purchased this item to celebrate the birth of my grandson.  I should have opted for real cigars, they might have tasted better. These cigars were very hard and hurt my teeth to chew. Not to mention that these gum cigars were much too sweet.
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: I've tried a lot of different K-Cups and this is the weakest K-Cup coffee I've ever tried. It should not be labeled "Medium Roast", it should be labeled "Warm Water Tasteless" Roast. Too bad I bought a large box. What a waste...
Example Output:
Negative
