I received the product in a timely manner. It was as advertised. I have used it a number of times and it works well although I haven't gotten the results from it I had hoped for. No fault of the seller or the product though.

Ex Output:
Positive

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.

Ex Output:
Negative
