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: This mix allowed my little one to have cupcakes at his second birthday party.  They turned out great and with some homemade vanilla icing, they were a hit with everyone!  I even used Ener G's egg replacer to replace the multiple eggs the mix calls for.  One hint, bake for almost the maximum time on the directions.  They come out golden brown and moist.
Example Output: Positive

Example Input: To get a more intense taste, I mix two packets in a 16-oz BPA-free Camelbak bottle, adding 8 oz of water and the rest ice, plus a packet of Stevia, shake well, sip, and oh so good! No-calorie sweet tea, green tea antioxidants, and I'm drinking a lot more water. I also carry packets in my purse and add to water in restaurants, saving tons of money from ordering drinks and not to mention calories. Although the Stash rep tells me there is a "negligible" amount of caffeine, the placebo effect gives me a great boost in the morning before my workout. Since I love mint, I think I've found the perfect product.
Example Output: Positive

Example Input: Just an FYI that "Yeast Extract" is one of the titles that MSG hides behind. MSG IS a preservative and a dangerous one at that. The package lies... these contain preservatives. I will not be eating these!
Example Output:
Negative
