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.
One example: 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 is here: Positive
Explanation: It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

Now, solve this: These chips are VERY GOOD!! I couldn't stop eating them. They didn't last very long. The reason I gave them 4 stars, instead of 5, is because I think the bags are a little hard to open. I'm not sure why they need to make a potato chip bag that sturdy, you may need some scissors on hand to open them much easier.
Solution:
Positive
