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: We used this cereal when my daughter was a baby 2 years ago and it was great. I ordered a case recently for my 8 month old son and it was spoiled! Amazon was great and refunded my money, but I am so disappointed with HAPPYBELLIES. There are obviously some major quality control issues that need to be addressed. I will be ordering baby cereal from a different company as I just can't bring myself to trust HAPPYBELLIES anymore.
Example Output: Negative

Example Input: Our cocker spaniel is now nearly 10 years old, and the solid gold food I'd been feeding him suddenly changed its formulation over a year ago(with no notice on the packaging), and he became subject to unexplained stomach upsets.  After the contaminated food scare even tho Solid Gold was not recalled, I decided to switch, and this formulation is perfect for him to not gain too much weight.  Newman's own is a brand I totally trust and have bought snacks for my human baby as well for years.  After a year on this food, my dog is doing fine, but I do notice a need to supplement with fish oil for a healthier coat.  That may be age related as well.  But the stomach upsets have stopped.  And I feel better knowing I am not exposing him to additional pesticides and hormones by going mostly organic with this formula.
Example Output: Positive

Example Input: My father grew up in Argentina and since he came to the States has been searching for the perfect dulce de leche that reminded him of his childhood. He doesn't have to search anymore, I bought him a couple of jars this past Christmas and he has been a happy camper ever since.
Example Output:
Positive
