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: A word of caution to anyone considering buying these: Read the ingredients first! I made the mistake of thinking they would be the same as the longer (Oberto brand) ones our local Costco used to sell, so I ordered up 10 bags to get the volume discount offered at the time. I knew something wasn't right as soon as I opened up the first bag and got a whiff. Then I read the ingredients and was shocked when I saw that they actually use pork hearts as the top ingredient. To eliminate any doubt, I tasted one.. we've been using them as expensive doggy treats ever since.

Output: Negative

Input: Consider Input: Just an outstanding product An authentic dulce de leche ranked number-one in Argentina for its exceptional richness and depth of flavor. Made at a small dairy outside of Buenos Aires. (note that the web page or supplier indicates "Made in Spain" but this product is clearly made in Argentina)

Output: Positive

Input: Consider Input: Totally not worth paying for. Even my kids hated this stuff. Very cheap cocoa in tiny tiny tins for too much money. I could have gone out and bought twice as much Swiss Miss, and enjoyed that a whole lot more.
Output: Negative
