Eric if you're really desperate all you need to do is fly to Ireland, rent a holiday home, visit a clinic that sells it, do an audiogram, buy it, give your rental address if totally necessary (probably not even required) and then go on your way.
I can't see why being from another country is any bar whatsoever to getting hold of this and indeed when
@Steve and Ross where discussing this neither did they.
The real issue is will it work for you and what is your reaction going to be if you fly around the world, drop 5k on it when all is said and done, and it doesn't work at all?
Can you mentally deal with that outcome?!? Might you be better off waiting for some reviews from Tinnitus Talk members and making a more informed judgement further along the line?
