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'.

We were unable to use this router because it was impossible to install. It requires software in order to be used, and a CD with the software is included. Neither of our household laptops have a disc drive, however. SO, I attempted to follow included instructions for downloading the software online. The web address given for the download is not a valid address. So I tried to find required software on the TP-LINK website, which proved impossible. Also attempted to call the company several times- sometimes I was met with a recording stating the number was invalid, sometimes put into a queue with a message saying all customer service people were busy, and then after several minutes of this, the call was cut off.
Output:
Negative Review
