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: Spectrum Naturals Walnut Oil, refined, is a very mild oil. I can't detect any walnut smell or taste any walnut flavor at all. Maybe that's what you want in some cases, though I was hoping for a more nutty flavor like raw walnuts.  It does have the advantage of having higher Omega 3 content than most oils. Also most oils that are high in Omega 3 (like fish oil and flax oil) have a strong taste which you probably don't want on your salad.  Unlike some of Spectrum's oils, it is not organic.
Example Output: Positive

Example Input: I have a Waring belgian waffle maker and was looking for a good batter to use. I tried this based on reviews and with add my strong recommendation for this mix.  It was very easy to make and the waffles had a wonderful flavor ... loved the malt flavor that came through.  I will definitely be buying more when the current mix runs out.
Example Output: Positive

Example Input: Way,way, way overpriced. When they first came out, I bought it at a Walgreen's for $5.99, and that's about what it worth.
Example Output:
Negative
