Sure. Listen, we had a real strong quarter, as you saw, and as you mentioned, approaching that $1 billion mark on a quarterly perspective, sales above 40%. I think really important here, Larry, is the user base. And this is a different kind of device business. It's a -- we talked about it from a mass market opportunity versus other parts of our device portfolio that might be a little bit more, let's say, call it, nichey versus the size of Libre. But the user base is super important because when you've got this kind of retention level that we're seeing on the product, so between 80% and 90-plus percent globally, it really looks more like a subscription-like model. And when you're in that subscription-like model and you've got this recurring revenue, the user base is hugely important. And I think that's a lot of our focus right here, as we talked about this mass market, is building the user base.
And I think we've done a really good job internationally and in the U.S. But as we've talked about, okay, we've got 3.5 million users. I've talked about numbers all the way up to 80 million users potential for this product once you aggregate insulin users and type 2s, et cetera. So I think this is a real strong growth opportunity for us, and we're still in the early innings, as I've said. From a road map perspective, we're not deviating from kind of how we thought about this, right, which is we will continue to provide superior technology, superior experience to the user, whether it's with the product, whether it's how they get the product and still a value proposition that makes sense for a mass adoption. So that's all gone very well, and that will continue to go very well.
Libre 3, we launched it in, I'd say, in Germany at the beginning of the year here. A lot of our focus in that launch, Larry, was just more to understand kind of our marketing messaging, our positioning with our existing portfolio, reactions from physicians and even look at how other users from other CGMs kind of reacted to it. And it's basically surpassed my expectations as we went into that pilot launch. And so we'll be now transitioning to full launch mode of Libre 3, where we've got approval. Specifically in the U.S., obviously, it's understood that the backlog that exists in -- at the FDA regarding diabetes products. And I'm not going to comment on kind of timing here or expectations, but just that we're very excited kind of to be able to bring Libre 3 to the U.S. also and augment our portfolio with the product.
