If he makes a mistake or she makes a mistake, we obviously have to fix that mistake. There is no, oh, I blew a transformer, it's going to cost this much. No, if you make a mistake and blow a transformer, then you replace the transformer at no cost to the customer to get them back up and going. That is what being a professional is all about.

Are you going to sell it? Be careful.
