[EX Q]: Worked like a charm all over England. I haven't tried the other adaptors, but I found my MacBook to work just like it does here in the US, and there was no difficulty plugging into the outlets.
[EX A]: Positive

[EX Q]: 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.
[EX A]: Negative

[EX Q]: The plot was terrible. The acting was terrible. The effects were as good as the other ones. If you want to see pure action without any story, then enjoy. Otherwise...it was a complete waste of time.
[EX A]:
Negative
