You will be given a definition of a task first, then some input of the task.
Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

I purchased this item a long time ago. It was easy to setup, and the sound was no bad. But the connector for the sub was badly made, I had to put it in a certain way so that the wires were well-connected. Otherwise it would start making terrible cracking noise whenever I put my book on the table, or move my chair, or produce a tiny little shake to knock the connector off its 'comfort zone'. At first it wasn't too annoying, but now it's much worse. I certainly will never recommend this to anyone.
Output:
Negative Review
