They are very secretive on manufacturing cost. I had came up with a thermostat and they will build it but they only say that it will cost $100,000 and a year to code. They do not say how much to make 1,000 units or how long. How do you know much to sell it for or when to ship (especially for Kickstarter campaign or working with other companies).
