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.
Positive

When the film first started playing, my partner and I looked at each other as if to say "What on earth is this?..." but we decided to give it a chance and let it play - for about half an hour before we couldn't bare to watch any more. The title says 'Funny' - it wasn't. The overall cover is totally misleading and gives you the impression it is a funny film by someone who had previously done a funny film - but it was in no way funny at all. The jokes were terrible, the script was terrible. Very disappointing.
Negative

Nice idea, poor execution. It simply does not work well, and is therefore much more trouble than it's worth.

Negative
