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 have ordered numerous teas, potions, lotions and other remedies...BUT have never had a lack of product in an order that was sealed.  The tea bag wrapping in question was sealed without a tea bag inside.  I would have said something sooner, however...I only tried these when I had a sinus infection and the last 3 times I tried to use one...the sealed pouch was EMPTY.  BEWARE!
Example Output: Negative

Example Input: This soy sauce is the best we have ever had.  Thanks to Amazon, we were able to find it again.  It makes a big difference when using this product.  Thanks again
Example Output: Positive

Example Input: I am disappointed since regular wheat thins don't have MSG, but this variety does.  I need to stay away from MSG, since I get migraines. I am sure Nabisco can find a way to make a flavorful cracker without MSG. These crackers have a very strong taste, and I found that the taste stayed in my mouth for a long time. I prefer the original, unflavored wheat things.
Example Output:
Negative
