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: 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: Love ur products but this one is NOT good. This photo is 8 hours after class. I’ve had this mat about a month and the stains never completely disappear. I’m a woman and I do sweat but it’s embarrassing to see the outline of my body at the end of class...to the point where people start staring at my mat and at me. Yuck. Please let me return for refund if possible.
Example Output: negative

Example Input: What can I say other than... it works. I have been using it for over a month if not 2 by now, and have had zero issues. It doesn't overheat, it's been plugged in at times continuously for days, and it's all been good and fine. Great after market option replacement or addition to your portability and power needs.
Example Output:
positive
