 I mean, like, you know, when I'm in Omaha, sometimes in our office in Omaha, you know, 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 if I'm having business meetings and dinners, and this hearing aid is still working. So it is remarkable. Talk a little bit about the different ones that are available. This is the Phonak. You've got others that you offer. Sure, sure.
