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 had been buying these treats for my cavachon for the past two years. He loved them.  The last batch was of noticeably lower quality...dry and crunchy rather than moist and chewy. I don't know if this is due to the shift in manufacturing from the US to China or coincidental. In any event, I will not be buying these any more and have switched to other treats.  Note, Amazon would not let me return this item, and I am within the 30 day purchase period. I'm not pleased.
Example Output: Negative

Example Input: I was really impressed with this.  There are many flavors, and quite a bit of heat.  With this and your favorite brand of cocunut milk you can make some great Thai curries at home.
Example Output: Positive

Example Input: It's hard to find quality gf products, and pamela's doesn't dissapoint. I always recommend this. I go through a lot of this blend with a family of five. Amazon helps keep it more affordable. The pancakes are great and the waffles are really good. I haven't tried it with much else yet, but my sister-in-law does chocolate scones  frequently  with great raves. I use the bread mix also all the time, and am very pleased with both.
Example Output:
Positive
