I'm looking to buy the amazon echo dot as a present for my brother, however at the moment he lives in Austria. I've read a lot of different advice about whether the amazon devices bought in the UK will work over there, but equally whether devices bought from amazon.de will then work anywhere other than Germany/Austria.
As his job may well lead to more travelling/living abroad but elsewhere, I would prefer not to buy something that could be useless, or rendered useless by him moving?!
Any help/advice greatly appreciated.
