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: Decided to purchase the 35 pound bag for my 12 year old dog who have skin allergy base on the positive reviews I've read on line.  Very happy with shipping & Packaging service from Amazon.  But very dissapointed in Premium Edge.  Not only did the food not help him, it seemed to made him worst the first couple of days! Also, the product says for adult dogs but on the package it also says from age 1 to 10 years of age???? My dog is 12.  I don't understand all the positive feed back for this product?  and I so regret for buying such a large bag or the product for that matter.
Example Output: Negative

Example Input: Arm & Hammer's baking soda is aluminum free, they just don't write it on their packaging.  I wasn't sure so I called them and they said there is no aluminum in it, and they would have to state it if there was because people take the product internally.  This leads me to believe that there just isn't aluminum in baking soda.  And researching it showed me that there might have been in the past, but not anymore and not for a long time.  I resent that Bob's Red Mill writes "Aluminum Free" on their package and then charges a premium for their product.  It's also arsenic free, I hope.  If they label it "Arsenic Free" will we assume other brands aren't?  I don't like that kind of marketing.
Example Output: Negative

Example Input: I have purchased these lemon drops for years and the company(Jelly Belly) has discontinued them.  I  bought what I thought was them on Amazon because they are claiming to be the ones from the Jelly Belly Company!  They are not and very disappointed they were misrepresentd as being the original...shame on you.  I now have 10lbs of junk
Example Output:
Negative
