This is just what I needed. Great price and fast shipping like always from Amazon. I was a little nervous about this purchase as another reviewer said this was not the officially licensed Nintedo product but it is. It is not a cheap imtitaion it is exactly the same thing that came with the DSI. As for durability I can not tell you because I just got it. But the one that came with the DSI only lasted 8 months so I guess maybe they don't have a long life.Get more detail about DSi AC Adapter.
