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: 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.
Example Output: Negative

Example Input: We love this coffee. It is the best K cup we've found. We like strong coffee and struggled at first to find one that we enjoyed. The prices on Amazon can't be beat and the shipping super fast.
Example Output: Positive

Example Input: I have to admit based on most of the reviews I was sold on getting the 48 pack.  Was a mistake. All three flavors had a distinct taste of the sucralose.  That is the name of the artificial sweetner, in the product.  If you like Splenda,you may like this.  But, it has a distinct taste. Unfortunately not for me. A few friends of mine that tried it and said,"It wasn't bad." Unfortunately, that was the best of the comments. If you really want a good cup of hot chocolate try Cafe Escapes or Swiss Miss.  Both are twice as good in my opinion. Liked the Escapes best.  Wish I liked the artificial sweetner, but the that taste has a distinct after taste. Probably would be better without the artificial stuff and more regular sugar. If your going to order I would get the small pack to try it.  Better then throwing out 30.  Try Cafe Escapes and Swiss Miss and see for yourself.
Example Output:
Negative
