Yes, David, it's a good question. I think everyone had exposure to ResMed products. We're the market leader, everyone knew the brand name. Everyone had tried it, and we get a large percentage of the prescriptions and actually the share in the 140 countries we operate in. But as you said, there are some doctors who liked a particular aspect or a technical aspect or an emotional aspect really or a workflow aspect of some of our competitors' devices or software systems. And to your question, they are getting, if you like, forced exposure, because it's the only one available for new patients, to ResMed's amazing innovation on the device, the software, the systems and the flow. And if they had some form of prejudice of device from the '90s that they tried or something and have been stuck with the brand, they're now trying a new brand. And I do think, to Jim's point earlier, that some of that brand-new share of somebody who was in another brand's componentry area says, wow, this actually is great. My prejudice was wrong. And I think we will get a lot of that share that we'll maintain forever. And I think certainly, the exposure of patients to the brands and to understand that has increased. I mean, the Net Promoter Score for ResMed amongst patients is rising, and the knowledge about the brands, for better or for worse, through this awful recall is, they're getting to know what device they have. And that awareness is actually good for the whole industry, because I think physicians and providers and technicians have always been aware of the brands and had prescription biases and others that we absolutely influence through our really strong commercial, clinical sales teams. And now we're getting that brand name to new customers as well. So I mean, the short answer to your question is, yes, we've got exposure to new consumers, new physicians, new providers. And we think a lot of that will be sticky because of the value we provide. The brand is the brand that represents 50% lower labor cost if you're setting up a patient when it represents three less clicks to get a report, when it reflects an API that can link into your Epic or your Cerner or your National Health Trust system, really efficiently, it becomes really part of your day-to-day workflow. And that's the type of share that we think is part of the ResMed brand and will maintain our strong growth for a long period to come through for this period.
