Task: Sentiment Analysis
Input (English): Review: I bought this adapter for my 12-inch G4 powerbook, one of the computers listed as compatible with this AC adapter. The specs all match up and it SHOULD work. But it didn't. The power would fluctuate and the computer would go back and forth between AC power and battery power, making the screen flicker and the battery never charged. I contacted MacAlly and they said they're aware of the problem but don't have a solution. Their answer to the problem was to return it, which I did.If even MacAlly admits it doesn't work, they really shouldn't keep selling it. All I can do is say don't buy this AC adapter. 
 Polarity: Negative
Output (English): True
