We

have two XNAVs and the Yomi robot.

And it all started with a conversation that I had with Mike Block.

He came to town to lecture at the Worthington lecture that we have every year.

And he was talking about implants and they kind of brushed on the X guide.

So I approached him at the end and asked him about it.

And he directed me to talk to Rob Emery, who was one of the developers.

What's the learning curve on like for someone that's thinking of getting that?
