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: I picked up a 3 oz bag of the Salt and Vinegar chips last weekend at Wegman's and in a blink of an eye, the bag was GONE. Very nice vinegar flavor. Bad side was in a blink of an eye they were gone which is not good for portion control. I ordered the variety pack in .8 oz size (single serving) to help with portion control. Most of the flavors I like - but fair warning, the parmesan garlic is VERY garlic. Love the salt and pepper. With 100 calories a pack, what a nice change from baked chips. Try it - you will like it.
Solution:
Positive
