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: in my opinion these are heads and twos above any pickle that you normally find at your local grocery store.  a lot of nice, sweet, pickle flavor.  I probably won't buy again off of amazon because of shipping charges, but if i ever see them locally, i'll buy a bunch.
Example Output: Positive

Example Input: My dogs LOVE duck treats and have been getting the chicken happy hips for years so I though I'd give the duck a try.  Bad idea.  The treat was too tough and stringy for my small female Westie to pull apart and she ended up choking and vomiting.  I order by subscription and had to make cuts in the strips with a poultry shear to use up the 6 bags.  I too hate the fact that these are made in China, but my little guys need extra condroitin and glucosamine so I'm back to the chicken formula.
Example Output: Negative

Example Input: I concur 100% with the other negative reviews.  My nuts arrived rancid and were not edible.  What more is there to say other than these Azar macadamia nuts were a huge waste of good money?  Two pounds of expensive nuts were tossed out in the back yard to feed the wild life and even the squirrels would not eat them.  I will stick with organic raw macadamias, preferably from Hawaii and a more reliable producer.
Example Output:
Negative
