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: I enjoy my Kavli Crispy Thins so much and so often that I now order by the case. Besides being naturally low fat and naturally nutritious, Kavli Crisp Thins are a great replacement for salty, fattening nachoes, and/ or pizza. With Crispy Thins, you can make your own nachos by layering the Crisps w/ chopped tomatoes, cheese, even ground meat ... pop 2 Crisp Thins w/ toppings in microwave, and  you've got your delicious nachos, (or pizza). I have Crispy Thins w/ melted cheese every morning ... great way to start the day. No, I don't work for Kavli ! This is not an ad, but a truthful review. Also so nice and easy to be able to order Kavli ( and just about everything) via Amazon.
Example Output: Positive

Example Input: Amazon sends you TWELVE boxes of these fabulous cookies and each box disappears FAST - in fact, DO NOT sit down with the whole box nearby or you will munch thru all of them without stopping! They are delicately sweet, crunchy, and buttery - without being at all greasy. You've been warned!
Example Output: Negative

Example Input: My daughter, living and working in DC this summer, introduced me to this product while home for a visit.  She encouraged me to give the plain version (just pure coconut water) a chance first, and by the second container, I understood the amazing qualities of this drink.  I felt so refreshed, hydrated, and healthy!  I later tried the kind with pineapple, which is also delicious, but I think the plain is more effective and purely refreshing when really hot, tired and thirsty, while the sweeter fruit infused version will be amazing as part of a cocktail.  Can't wait for 5:00!
