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 bought this to live in my backpack to charge my Asus laptop away from home, and it works perfectly - no different from the Asus charger except the form factor and lower price. Both positives as far as I am concerned. I've already recommended this company to others looking for replacement or spare chargers.
Output:
Positive Review
