Sure. This is Bob. So the legal and professional, I would characterize as maybe not permanent, but I can't call it one time either. I think with, all the different things that we've got going on and trying to advance a business, I think will be in that run rate for a little while here. But it's probably not permanent, as far as the OpEx savings on the move. We did, we will save one facility, but I wouldn't, from a modeling perspective, I wouldn't factor in net savings. I think, it'll be a little bit more expensive actually, as we once we get done with everything, the other facility that we're consolidating out of, we actually owned. So I wouldn't build anything from a savings perspective in your model for that consolidation, but Mike, you can't model in, if you don't have enough parking spots for your people, you know, park being in the grass or the parking on the neighbor's parking loft, the facilities we had were I'd say, minor league at best. How's that? So the recruit people in now, we have a world class place, well lift, well equipped, not parking, big prototype area. We can actually fly drones indoors when we finish the prototype center, it's got high roofs. So I'm proud to be sitting there now versus before I used to be embarrassed to bring some people in to get interviewed here. How's that, can't put a number on that. And I would say, especially as the finance person, that it's hard to put any kind of numbers on this, but just having people in the same room, the collaboration's already improved just in the short time and can't value that, but it's definitely been powerful.
