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 good construction, not the usually cheap plastic feel. I love the multiple colors on each truck. The return mechanism is really nice and fun. It's a must buy for every child!
Example Output: positive

Example Input: After a year of this product working fine, our internet provider recommended we do a hard reset of this device to improve the connection between this router and our modem. That's when the problems began. Netgear spent over 30 minutes on the phone with us, found the issue and then wanted $139 for further support, more than we paid for the router initially. Escalating to a supervisor he offered a lower price but no other options other than a troubleshooting article we could have found ourselves (if we had internet connection). We have lost a day of work, still don't have internet, Netgear doesn't care in the least.
Example Output: negative

Example Input: I have a small wrist and love styles like this where all the excess strap is tucked away. This is as comfortable as a sport band but the leather classes things up. I want it in more colors.
Example Output:
positive
