In this task, 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: With only a couple of swims under my belt, there is a marked improvement in leakage and fogging. Comfortable on my eye socket/face and the goggles come with additional nose pieces. Product is 'hair friendly' and attractive. It took me a while to figure out the straps, but I 'get it now' and like them.
Example Output: positive

Example Input: This cookbook isn't simple, as claimed. I bought it for the photos and supposed ease of recipes, but the truth is most of the stuff in there is flavorless and more difficult than necessary. The most frustrating part, aside from it not being recipes most people really eat, is that the 'simple' recipes require having other recipes made before-hand, and then lists them as an ingredient. I sent it back.
Example Output: negative

Example Input: I've had this for MONTHS now and it's truly one of the best mats around! I got two sizes.. the smaller one for my computer and the larger one for the kitchen. I also love that it's super easy to clean. Great product!
Example Output:
positive
