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: While I typically like the Happy baby products, I was very disappointed with this product. Unfortunately when I opened the first of six containers it smelled stale as if it had been sitting on the shelf for a very long time. I decided to mix up a bowl but after tasting a bite, it confirmed my initial thought--it was old despite the expiration date. My guess is that I received a bum batch however, I am not willing to try it again when there are other organic cereals I have been happy with. I will say I was extremely pleased with Amazon's customer service. Although this item was non-returnable, they still issued a refund to me promptly.
Example Output: Negative

Example Input: I baught this kind of cereal from Wholefood. Since this was the first time I tried this brand, I picked 3 kinds: multi-grain, oatmeal and brown rice. Oatmeal was all right, but the other two smelled like they were already stale(the expiration day is May 2013), and they tasted bad too and sticked on my throat when I tried them. My baby cried and refused to eat them. The customer service of Wholefood was very nice and refunded me. I don't think I will buy this brand of cereal again.
Example Output: Negative

Example Input: This was a great selection of hot sauces, with a good variety of flavor. Each of the different bottles had a unique taste and each of them had a heat around the same as tabasco sauce. Oh, except for the Dave's Insanity. That will have you pleading for the sweet release of death. But the other sauces are very tasty, and very usable in everyday cooking. Recommended.
Example Output:
Positive
