Query: Incredible!

Can't believe how quick and accurate this controller is. I've been disappointed before by other wireless products, but Logitech really seems to have this technology down! This thing is so amazing, that I keep motioning as if there's a wire attached to the controller whenever I shift my feet. This is also by far the best price anywhere... I've seen this same controller elsewhere for $50.
