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 started using <a href="http://www.amazon.com/gp/product/B008EMA3AS">Lourdes Gourmet Chimichurri Sauce</a> on my grilled steaks and fell in love with it.  Now I'm putting it on my chicken, vegetables & pasta.  I'm turning into a real chimichurri addict.
Example Output: Positive

Example Input: These are great because they're only 100 calories per pack and are just as good, if not better, than other chips out there.  The "Original" style taste exactly like Munchos, but don't come with the high calorie count.  The other flavors (Sour Cream & Onion, Salt & Vinegar, Salt & Pepper, Cheddar, and BBQ) are all delicious, as well.
Example Output: Positive

Example Input: I have used this product for a few years now. This being the first time from Amazon. I'm glad it was there. This is by far the best pancake/waffle mix on the market bar NONE !
Example Output:
Positive
