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: My dog will do anything for these treats. Buying a five pound bag lasts about a year and they are dry so they are easy to put in your pocket and they last forever.
Example Output: Positive

Example Input: Please ignore the one-star comments, if you check the bag the main ingredient IS in fact whole grain brown rice and the second is rice flower. With anything that is gluten free you have to add another "binder" which is where the corn flour comes in. For someone who has celiac disease and cannot have Sunchips, because they contain wheat (a key binder to any chip, cookie or cereal) this is an excellent product. My spouse and I buy these a lot because they are gluten free and absolutely delicious!
Example Output: Positive

Example Input: I was pleasantly surprised by the stronger than I expected ginger flavor in this product. It is excellent, if you like ginger, try this. Best on hot biscuits! Update. I've just reordered, wish they sold it by the gallon, its different, something you can't find locally and excellent.
Example Output:
Positive
