Update via Aud1073cH in the comments: "I've got one of these-
Sharper Image has their name on it, but it was made by Vocolo. The same people that brought us the Vocalizer 1000. (Just search for Captain Kazoo on YouTube.)"

Update via john in the comments: "No - not made by the same people that made the Vocalizer. I know, because I am one of the inventors! :-)"
