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: This product is great. I have been searching for an easy to use and non sweetened green tea. So many of the teas are sweetened with Splenda type sweeteners and I prefer to use Stevia. The Jackie Chan green tea appears to have been discontinued. I mix this product and love the taste. A little lemon and Stevia and I have the perfect evening iced tea. It provides all the benefits of green tea, and the instant convenience. I give it five stars
Solution:
Positive
