I get that. In terms of my expectation, $129 is not so affordable, but I understand it's a beta kit and you're in very early days. I would assume that there is upfront significant investment and you would imagine, down the road, when this is up and running three or five years from now, that those costs are going to come down. I wonder, though, where you would imagine those costs coming down to.
Ms. Cooper, you're starting at $129. Do you have a sense of where those costs might go?
