Example Input: This brush is a snow and ice BEAST! It is, perhaps, the most solidly built brush and scraper, with easy extension and easy rotation of the brush to change its angle relative to the shaft. As it is a new purchase for me, I'll have to update this later in the snow season. And, frankly, I'm hoping that I won't need it again this season. But I am prepared! Fast shipping, and excellent follow-up by the sender. highly recommended.
Example Output: positive

Example Input: I ordered the Hot Chow Chow and received the mild Chow Chow two days late. This is a non-returnable item so I'm stuck with it. I can buy mild anywhere. The Hot is hard to find. Disappointed with this supplier.
Example Output: negative
