[EX Q]: Review: I am fortunate to be a student in Naader's yoga classes at Yoga Kingdom in Pasadena, CA. As someone who has studied yoga on and off for 25 years, i can confidently say that Naader's class is the most complete and well-rounded I have ever taken. For those in other parts of the world who would like access to an energizing, healing yoga workout, I would highly recommend this video. 
 Polarity: Negative
[EX A]: False

[EX Q]: Review: I'm now on my third charger for my Powerbook (my dad says I'm rough on equipment). Let me tell you, the Macally is NOT it. Like others, it fluctuates between charging and battery every 1-2 seconds and the brick makes weird squeaky noises. After not having a computer for a week and being so relived to finally get this charger, I was almost in tears to find that it is a piece of crap. It charges when the computer is off or in sleep mode, but that's not going to cut it. If you have a Powerbook G4, don't waste your money on this. 
 Polarity: Positive
[EX A]: False

[EX Q]: Review: You aren't saving any being this adapter. I purchased this for a 12" G4 Powerbook. The power it supplies goes on and off constantly. This can't be good for the computer. It certainly doesn't charge it. Don't waste your money on this Macally adapter. Try to find an original Apple adapter if you can. 
 Polarity: Positive

False
