John,
I have had multiple video appts with Mayo and the you tube video really does not tell you how it works. It is to simplified. You definitely need ZOOM software to use. The PDF Mayo has with instructions explains better. I have attached file.

The 1st video appt. I had, the dr could not get ZOOM to work on his computer. The 2nd appt with different provider I had yesterday went better.

They are OK for quick check in. But for anything more in depth, I would prefer in person meeting.
