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: Works well. Needles seem to be a bit too thick. Worried that using this may damage my basketball. Have used it twice and it has worked well so far, however. UPDATE: I used this pump for a third time on my Wilson Evolution Basketball and it pushed in the rubber circle into the ball, popping it. Need is TOO thick. Buyer beware
Example Output: negative

Example Input: I got these headphones for two reasons: 1. I wanted something to put in when I ride on my indoor cycle trainer in the winter and watch movies. 2. I was sick of my headphone cable getting caught on stuff at the gym. These headphones have exceeded my expectations. They sound surprisingly good and connect easily to my iPhone. I haven’t had any issues with connection dropping and the battery lasted a lot longer than I thought it would. Please note that I am rating these based on what they are, and not on what they are not. These are not audiophile headphones. They don’t sound mind-blowingly good. In my opinion, they sound better than the EarPods that come with my phone. Not way better, but better.
Example Output: positive

Example Input: I had to throw this away. I really wanted to like it and tried everything! I added cheese and butter, broiled it, toasted it, even with bacon added to the cheese and butter, it was still spongy and inedible.
Example Output:
negative
