 When I get up in the morning, it goes in. And it stays charged all day. There are no batteries in this thing. Isn't that nice? It's amazing. I put it in the little charger gizmo, go to sleep, get up in the morning, put these things in, I'm set for the day. And if I have a 10 or 11 or 12 hour day, it's still working. When I'm in Omaha, sometimes in our office in Omaha, I'll start working at 7 in the morning. I won't be back to the hotel to go to bed until 9 o'clock at night.
