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.

Example Input: You can find this 6-pack for $40 dollars less at diapers.com. No reason they should be charging this much.
Example Output: Positive

Example Input: So far, I've only had time to make waffles with this new GF Bisquick, but they were delicious. Sometimes with gluten free products, you have to use other weird ingredients, or processes to make them. These waffles were super fast, easy, and seriously delicious. Can't wait to make other things!
Example Output: Positive

Example Input: My German Shepherd took less than 1 minute to take off each cover and that included the time to eat the treat. I was looking for more of a challenge for him. Guess he is one of the too smart for his own good, or at least too smart for this toy. The one star is for my dog, it might work well for others.
Example Output:
Negative
