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.

Let me give you an 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.
The answer to this example can be: Positive
Here is 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.

OK. solve this:
I really enjoyed these beef sticks. Even though I preferred them to be a little bit harder, they were tasty. I just put them in the frig and that worked out fine. Nice flavor, not too sweet or spicy. They sure didn't last in my house!
Answer:
Positive
