question:
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.
answer:
Positive


question:
If you believe people have an eternal soul, this book is not for you. If you believe death is the end physically and spiritually, and you want your child to believe that, maybe you will like this book. I found it not comforting at all, and not what I want my child to believe.
answer:
Negative


question:
After reading this book, I felt guilty for having purchased it, because that contributed to its best-seller status. (Oops, maybe not; the way it works now, it was a bestseller the day it hit ths stores.) But it is sad to think of all the aspiring writers who struggle to get a publisher's attention for their worthy efforts, while this strangely hollow piece waltzed its way to bestseller status. Some editor should have thrown cold water on this potboiler.
answer:

Negative
