Question: This product does not work with my ibook G4. As stated by some earlier reviews by other customers, the charger toggles between charging and not charging. Occasionally, if it is left on, it will continuously charge. I thought about keeping it, but it is unreliable and there are other third party options for $10 more.This one is going back to Amazon.

Question: I bought this adapter almost two years ago and it still works-kind of. The insulation on the area of the cable where it enters the brick has become damaged, exposing the outer wire. I taped it up, but there is always a connection issue, where the AC indicator at the top of the screen will often flash to battery power and then back to AC. I keep the AC adaptor in the front compartment of my backpack, so it sees some but not major abuse. I'm sure this won't be an issue if you aren't traveling with it, but I just thought I would relate my experience.

Answer:
Negative
