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: This was my first experience of a bad Darjeeling - before, I hadn't known there was such a thing. The first brew yielded a dark rust color tinged with olive-green. The bottom of the cup was invisible. The taste was sharp and astringent. Thinking I'd brewed too long or too strong, I set the first cup aside and tried again. And then again. A light brew of 3 minutes improved the clarity; however, nothing I have tried since has removed a level of astringency and a furred taste that I associate with lesser teas. The wet leaves are the typical size, light brown but unexpectedly interspersed with limp green squares. The aroma of dry tea in the bag reminds me of old hay - neither moldy nor spoiled, just old. In contrast, the Davidson's Keemun Conjou which arrived in the same shipment smells and tastes like delicious Keemun Conjou and nothing else. Given the price, I knew I was gamboling and consider this a lost bet. I have given the product two stars instead of one, because I haven't thrown it out (yet). I keep a supply of Lipton's bulk tea for emergencies such as long periods of unemployment, and I don't really need more emergency tea. Perhaps it will work for iced tea. By no means am I an expert, but I do value tea, and so I hope this opinion helps other buyers who are trying to decide between two Darjeelings. Davidson's ships quickly with value pricing, and so I am not giving up on the merchant. Just on this particular Darjeeling.
Example Output: Negative

Example Input: This is the 1st K-cup coffee that I am getting grounds in my coffee. It is occuring about every 3 cups. I have not had this problem with other K cup manufactures. I will not reorder.
Example Output: Negative

Example Input: I purchased this product as an alternative to a rawhide. Our 5 month old German Shorthair Pointer puppy ate it in a matter of 6 minutes or less. She loved it, but it was more of an expensive treat. With a puppy, I needed something to satisfy her chewing urge. The treat fractured into small bits all over the floor but our dog was willing to pick those up. The pieces looked rather sharp and that was a concern. Others mentioned it was made in China and I would like to add the first ingredient is corn. It might last longer for very small dogs.
Example Output:
Negative
