Yeah. It's an interesting one. And, Brett, it was a product that we have had for a while, and we've held partly because we had a lot of other stuff to sell and launch. And we were testing it. We actually tested that product for almost a year before we put it in the market. And I'll tell you, the reception has been really terrific. I just spoke with our US folks yesterday. And one of the things I heard which was exciting was that the -- we're getting more than half of our -- of this coming from the two-week and other reusable market. So, I think that's what we had hoped for. And I think that's exactly what we're looking at, which is -- the notion of a two-week replacement is not intuitive, right? Patients forget, docs worry about that. And what happens in truth, I think, is when their lenses get real gritty, they decide to replace them, instead of doing something that's a little bit healthier for them. When you get into a much more intuitive replacement schedule, every Monday, every Sunday, whatever it is, it becomes a much more reliable idea. And that is what they're reacting to because optometrists are principally concerned with the safety of these patients and how they handle the health of their eye. And so, if you can get them on a schedule that's, A, shorter, but B, still affordable, and C, then rememberable, if you will, that is a very appealing idea to most optometrists and I think that's what they're feeding back to us. So, with that said, I did comment on the size of the market. It's meaningful and we'll see how this takes shape. I mean, I am positively predisposed to believe this is a good product to launch and will give us a nice incremental contribution to the reusable space.
