Hi German Guy,
I heard about it.
I`m told too, that this is a easy way to try vns, in the future.
So if you can wait until that time, i think its worth waiting.
But for my son, it shouldn `t be usefull.
He should not accept that "thing"behind his ear!
But that is the problem for children with special needs.
I also heard of another device, with a rechargeable battery:

But i`m wondering, what will be really good in the future.....
Who will really know?
