Well, that doesn’t happen, Matt, until you actually submit the PMA. So, submit the PMA to FDA before you get on their schedule. So, we have to make sure that we can -- we have to complete all testing. So, as you can imagine, starting in the middle of March, everything was shut down, and things get backed up and everybody wants to get to the starting line, when things open back up. So, that’s what we’re in position to do. And these vendors are doing their best to open back up, they are all over the country. Sometimes you get lucky or unlucky depending on where you -- which site of their you were scheduled to be in. If you’re scheduled to be in a place where there’s not a lot of COVID, then that’s great; schedule to be in place with a lot of COVID, that’s problem. If you schedule to be in a place where there’s been a lot of protesting, it’s problem; if you’re scheduled to placed, where there’s not a lot, not a problem. So, these are things that just you couldn’t have predicted four months ago, when you were setting up all these logistics. You couldn’t think of these things impacting your business plan. So, kind of a global pandemic is a new one for us, I’m sure it is for everybody. You kind of kind of don’t expect it, you don’t really know how to plan for it. So, we’ve reacted well with keeping these timelines pretty tight in terms of couple months delay here, it could be much worse. And we’ve worked very hard with our suppliers and partners out there to make it a very short delay. So, again, I don’t know what else you want me to say in terms of testing. I mean, I could -- we could rattle off 15 different tests. But it’s just -- electrical safety and adapters, things like that. This is a medical device certainly.
