Given the task definition and input, reply with output. Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

I bought two, one each for my wife and me. \"Hers\" does not work at all. It provides power to the battery and the light is orange as if it is charging, but it never charges the battery. \"Mine\" does supply power to the battery, and the light is a bright green, but it charges the battery only on occasion. We've had them both for less than a week.<br /><br />Guess I'll have to splurge and buy the expensive, but real, Apple cords. My wife and I both use our computers for work and need more reliable power and charging than these things have provided.
Negative Review
