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 Output:
Positive


Ex Input:
This book is a very informative, yet easy read about the realities of life and how patterns are repeated sometimes even unknowingly until honestly addressed and changed. That is where the power of this book lies in giving insight, tools, all with a touch of humor to make positive changes of direction in our lives. Highly recommend.

Ex Output:
Positive


Ex Input:
I love this record. And I am also a big fan of remastered re-releases (Bowie, Roxie, etc.), but I was disappointed in the sound of this remaster. My Import version sounds MUCH better...a lot more raw, more vital, better definition between instruments. This sounds like a lot of compression, and not much more. Buy this record, but don't re-buy it for a better experience like I did.

Ex Output:

Negative
