Task: Sentiment Analysis
Input (English): Review: I bought one of these adapters about a year ago to replace the original apple charger that came with my ibook G4. The Macally worked fine for about a year then died; since it lasted as long as the pricier apple one, I decided to go ahead and get another one. The new adapter - which is listed as exactly the same product I bought the first time - is physically different, and I think is not really compatible with the ibook G4; the charger doesn't always connect firmly to the laptop. And it could be a coincidence, but in the month since I have had it my computer has started having sudden power failures when running off a/c power (but has no problems running off battery). I guess I will be shelling out for the apple adapters in future - this one seems too risky. 
 Polarity: Negative
Output (English): True
