TASK DEFINITION: Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.
PROBLEM: Possibly the worst product I have ever had the displeasure of buying. Within a month, the wire near the connection to the laptop frayed open. It does not charge the battery very well and slips our of the laptop frequently.

SOLUTION: Negative Review

PROBLEM: This makes it easy to plug in my iPad. I don't know why Apple gives you such ridiculously short cords. But they do so I turned to Amazon to buy this one and it works great.

SOLUTION: Positive Review

PROBLEM: Like everyone else I was drawn to this battery for the price. However, once installed my MacBook Pro failed to recognize it even after an overnight charge. Also, like others have said the battery is not a perfect fit. It sticks out of the body of my computer about 1-2mm. Not enough to be a real problem, but certainly enough to catch enough material to collect or take the brunt of the scratches. I then began the return process through the Anker website. Their response was "We just got an upgraded model for this particular battery stocked,just wondering if you could give us a chance to send you a new unit for a try? Or if you still prefer to get a refund,we would be glad to assist you." So why did I not get that "upgraded model" to begin with? It hadn't been more than a few days since I had placed my initial order and I find it hard to believe they had "upgraded" within that time. Long story short I followed through with the return.

SOLUTION:
Negative Review
