PROBLEM: Review: I bought this to replace the supposedly same power adapter that I purchased last year. This is NOT the same adapter as pictured for the item (I see that a customer has added two pictures of the true product). I was not concerned with this difference but would have preferred to have a light indicating the power is on. At first, it seemed to power my powerbook G4 fine, but later it started to cycle as charging and not charging, thus making the screen brighten and darken. When I shut the computer and let it charge, it did charge some, but I'm concerned about ruining my battery (which is also a replacement). It simply does not work when you are using the computer..and I'm ALWAYS using my computer! I will have to find an alternative to this product. I thought it was bad enough that the one I got last year quit working, but this is ridiculous. 
 Polarity: Positive

SOLUTION: False

PROBLEM: Review: just got this charger yesterday to replace my broken apple charger.All this charger does is allow me to turn on the computer (sometimes), it does NOT charger my powerbook g4. 
 Polarity: Positive

SOLUTION: False

PROBLEM: Review: The set is cute to look at, but as far as actually using, it is terrible. The glasses are fine, but the shaker is so hard to use, I actually took a chunk out of my finger trying to get it open to refill it! I've never used it again. 
 Polarity: Negative

SOLUTION:
True
