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: Really does a good job of pulling the dialogue out on the tv shows. Over all sound is great. Lots of available adjustments which I really like. I added a woofer and it works great with the sound bar. We are very happy with the purchase.
Example Output: positive

Example Input: Great band, very comfortable. Easy to adjust and I like that it has a little "give" when you bend your wrist unlike the silicone. I don't like how silicone bands for the Versa the metal clasps can pull away or break apart from the silicone over time and these are built into the plastic, making them much more durable long-term.
Example Output: positive

Example Input: I love these. They don't spill easily. Only through the straw. However, when you refill, you have to take the straw out before putting on the lid, the suction makes the liquid come out of the straw.
Example Output:
positive
