Ok, I have a close friend, actually a German who we hosted for a year as an exchange student. She lives in Germany and want to buy me something for my 50th birthday. Immediately I tohught TUNZE (and VW) but Tunze is prob more in here price range. So my question is, if I had her pick me up a nanostream, would I be able to use a German model here in the US? I'm asuming I would need a voltage convertor ofr something, correct?
