You will be given a definition of a task first, then some input of the task.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

We purchased this tripod for one of the larger Sony cameras that we also purchased through Amazon. The camera is awesome. The page for the camera recommended this tripod so we bought it from Antonline. This tripod is not nearly strong enough for use smoothly with our camera and when I contacted Antonline for a refund they refused to deal with me, even if I paid the shipping back to them. If you buy this tripod, beware that truly strong remote control tripods can start at $300 and go up from there.
Output:
Negative
