You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the 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.

I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Solution: Positive
Why? It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

New input: Used it a couple of times over the course of a month, and it worked great! Third time, high pitched noise, and no mic signal coming through. Not too surprising, given how flimsy this thing feels. This is apparently a known issue, just look at other 1-star reviews of this product. 'Nuff said!
Solution:
Negative
