Example Input: These chips are too salty!!! I like the crunch, size of the bags, and variety. But i cannot finish the case due to how salty these chips are.
Example Output: Negative

Example Input: Chips are not as tangy as I hoped or expected. Poore Brothers is a better choice for the "hard-core" Salt N Vinegar fans.
Example Output: Positive

Example Input: <a href="http://www.amazon.com/gp/product/B000GWLUGU">Plocky's Tortilla Chips, Red Beans 'N Rice, 7 Ounce Bag (Pack of 12)</a>  I first tasted these chips while visiting relatives in KY.  They are not available where I live, so I ordered them from Amazon.  WOW!  My friends and family are all addicted to them.  The spicy flavor grabs you at the first bite.  Once a bag is open, it is gone!
Example Output:
Positive
