In this task, 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: 4 times now I tried to order this DVD--twice from elsewhere, twice now via Amazon, and ALL times I was sent Blu-ray even though I ordered DVD! The DVD is listed separately from blu-ray: the boxes are different, so I zoomed the photo claiming the "DVD" format, ordered clearly under the "DVD", and under the lower DVD pricing, as Blu-rays are sold at a higher price. Each time I am sent the Blu-ray!!!! I am so frustrated at this terrible advertising! Why is the photo/descrption/price for DVD offered online if only Blu-ray is available? Blu-ray doe NOT work on my DVD player and just want what is clearly marked as offered!
Example Output: negative

Example Input: Love the feel of the sheet set but very disappointed in the cooling effect that your website describe. It is not at all cooling when sleeping. In fact tit gets really warm and still waking up sweating. This purchase was completely unsatisfied. I washed it so I have to keep it. I am very disappointed in this product.
Example Output: negative

Example Input: This was a gift to my sister and the other day at dinner she was telling me how much she loved it! That made me so happy because she is super picky. She says that the case is easy to take off her phone, (it has a magnetic top piece), as she prefers to charge them seperately so they are juiced up and ready to go. She said it's easy, click of a button to get it to charge your phone when you are low on battery. And she really adores the rose gold color; I do too, it's really cute. Great buy!
Example Output:
positive
