not much here
While it's true you don't have to worry about the batteries going bad, you do have to use it for a looooong time for it to do it's stuff.  Not much power and no way to tell what "speed" it's in.  You have to turn it on and cycle through the speeds to find the one you want.  Got it for the wife and she went back to the battery operated one she had.  Except for the lack of batteries this is not what expected.  The cord is okay, but could be longer.  Like the other reviewer said no where on it does it say Hatachi.  Would not recommend if looking for a good toy/massager.  Very DISAPPOINTED!!!
