Yes, so competition, right. So, the competitive response evolves right as we gain success, when we first came out the competitive response was fairly simple. They're not on contract, kick them out. And they have no clinical data. Sure, their primary data is interesting but clinical data, right. So we've largely solved those two counter details, counter punches, right, we've got excellent clinical data emerging of course, we need more, and we’re collecting more in terms of retrospective series, et cetera. And we need to finish off BRAVO 1, to have the full complement of data at two years. But you can see that the BRAVO data looks just spectacular relative to competitive products, and BRAVO 2, which will be robot specific studies needs to get going as well. That's been delayed due to COVID. But we have some interesting ideas on how to jumpstart robotic datasets there. So, we've shifted now to a point where clinical data and contracting are in place. So interestingly enough, we're just seeing usual Medtech hand to hand combat kind of tactics, right. I mean, there's been a rash lately of what I’ll call little ticky-tack studies, you know like put a piece of plastic in a pouch and infect it with bacteria and compare it to OviTex. And, if the bacteria eats the biologic material, it must be bad. Well, that means nothing clinically, right? It’s sort of like a rig test. And we've seen little ticky tack trials like that, using enzymes and things like that. So, it's good, it's healthy, we have the answers to every one of those little preclinical studies that they're throwing at us because we feel super confident in the product set, clinical data is awesome. It's very consistent, not just with BRAVO, but with the rest of our clinical data. We have about 500 patients aggregated in various studies, from everything from robotics to inguinal to complex mental, and we even have some surgeons that have done 100% conversions. One of the guys that's going to be speaking at the KOL event, I think he might have 500 procedures under his belt, just on his own. So, there's just a drumbeat methodical, steady, disciplined and that's just the way we're going to do it, right. So sure, the flack will come at us. Right now, I wouldn't consider the flack to be anything out of the normal that I've experienced in my career, hand to hand combat in the field in the LR with surgeons.
