Yeah. I'll start with the China and move backwards, Jon. And I'll get John involved here, too. But from the China side, obviously, we saw what you published there, whatever, but I looked at Angel numbers, and it basically same thing we experienced. I mean, we experienced a shutdown of Shanghai, slowdowns in some other regions, and there was nothing in those numbers that really surprised me. As I look at China, our ability to compete there. I feel great about it. And again, our investments we've made there in treatment planning and manufacturing. We've only added to that. The efficiency of those organizations have done well. Our product is great for that marketplace, and some of the most difficult cases that we encounter exist there, too. So I feel good about our ability to compete in that market against Angel or anyone else who's there. We just need a stable marketplace that we can operate in, and it hasn't been stable for -- goodness knows, it's been, what, almost two years. And I mean I just read this morning, the Wuhan's looking at the close down. So I mean, Jon, there's a lot of variability there, a concern with COVID and shutdowns, particularly in the second half of this year in China, but I continue to be concerned about that can disrupt the marketplace. But if that stays clear, we're going to have China in the second half that we can operate from. To answer your question, I feel good about our competitive position there, our ability to compete against with anyone.
