Sure, of course. Jon, let me just answer the Spark first and I'll come back to N1. We have enough capacity. We have built enough momentum, manufacturing capacity to deal whatever is ahead of us in 2021. We doubled the capacity in Q3. We're continuing to add capacity. The case submission has come through. And we are optimistic about what we are seeing here. And as I said, the combination of bracket and wire and the clear aligner has really reenergized this segment as a whole, and we have just continued to add to it. So we do not have a capacity challenge.
Furthermore, since mid-August, we have been able to reduce the turnaround time by over 40%, and we have been able to maintain that. So answering the question, we are excited about it. Team has been doing an incredible job using EBS to improve productivity, quality, delivery. And we think that, that trend is going to continue moving forward.
N1, obviously, is approved in Europe. We have launched it in 8 countries across Europe already. Obviously, the COVID situation has had some impact, how many of them can we do face-to-face. But we have it in the hands of over 100 customers so far. We are getting great feedback, and we are seeing the orders are coming through, and we're going to have more of a measured rollout, and we are building additional capabilities around this with abutment and prosthetics option, which is going to help us to roll this out a lot broader.
From an N1 and FDA approval, we're in the process of working with FDA, answering questions, and we're going through that process. We don't have any specific time line. A lot of it has to do with how quickly this process goes through. We're considering this to be available in the United States, more in the second half, later half of 2021. But we think the combination of activities that we have done around commercial activities, new products, should put this business in a more of a mid-single-digit growth as we go forward.
