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: I have purchased this product in the past through Amazon for my twins and it was good. However, the last time I ordered the 6-pack in June, the cereal was stale and smelly. I opened a few cans and they were all the same. I called Amazon customer service and they were very helpful and gave me a refund. I don't think I will purchase this item again through Amazon, although I do purchase the majority of items for my twins(including diapers) at a great price from them.

Output: Negative

Input: Consider 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.

Output: Positive

Input: Consider Input: The popchips are a nice alternative to potato chips. They are not greasy and only 100 calories per bag. Great for dieters. Fits in with a low calorie diet. Definitely would recommend trying at least once.
Output: Positive
