 2018 M, and it's been a lot of years since I even thought about that. In 2017, we released the M, and things started to change for us in a pretty positive way. The 2017 was the first time that I kind of took what I learned basically over the course of a year in an actual true CNC, and then applied it to make changes and make something new. Beginning in 2017, six or seven people. We had one real CNC machine and two kind of small, basic hobby CNC machines, you know, that we got from Tormac. But we only had one real CNC machine to actually do production, and that's where the 2017 and 2018 M's came from. So this is pretty exciting here. We are making M stems, but we're making 2018 M stems. We had 1,500 square feet of like shop space, and we had roughly like four machines in it, you know, which occupied like everything. When it came to changing the machining for the 2018 M, what did we really change? Well, the kind of answer didn't change. The tip we added an extra set of grooves around the same spiral, so that was actually one of the simplest things that we could change. Where we spent the most time was in this grip area. So we moved the logo right next to the airport now, instead of on the other end, and we put this nice texture. That's the sound of the texture right now. It's like, you know, it might be nice to have maybe a little grip section here where the logo was last year. So we started with this cool kind of spiral pattern. Then we ended up with actually a straight cut pattern, which is just kind of fun and different. Almost like knurling, but not quite. So gave it a little bit more of a tactile grip than we had on the 2017. And then when it came to the tip, we decided to make it a double triple helix instead of just a triple helix. So there'd be a little bit more of an air path for air to flow between the cap and the tip. Originally kind of engraved kind of an M shape on the back of this one, but this one didn't quite make it into production. We just ended up going a little bit more simplistic. We've changed the design a little bit, and I think made some very nice noticeable improvements. That'll bring some additional value to this product. And at the same time, we didn't have to substantially increase the cycle time because as we continue to learn about our machines and find new and better ways to do things, we're able to make a better quality, more complex, more functional product in about the same time. Just as we were starting to work on the design for the new 2018 M, I was able to successfully sign a lease for the building that we're in now at Gene Street. Moving to this facility and whatnot, it was kind of like the beginning, really. This is our new shop. Just signed the lease, and we started cleaning up and painting the building in January of 2018 and started moving everything over. In fact, you should have some very good video of moving the CNC machines and loading them on the truck and pulling everything out of our location on Norway Grove, where all the shit piles were, and moving down here to Gene Street. That was a pretty big deal for us that day when we literally moved almost our entire business over the course of one day. So the M became a really important part of our company come 2018, and as our first reason and our first trip to go to Europe as a company, we took the M to Spannibus. It was a really exciting moment for us doing demos in Barcelona, showing people the M, doing a few giveaways, and at that point working with what was our largest account in Europe, it was Vapo Shop. They were gracious enough to give us a spot in their booth, and we worked the show and we sold M's, and it was an absolute blast. In general, the response for the 2018 over the 2017 is, oh, the airflow is a little bit easier. Well, that's what we're aiming for when we add another airflow channel. 2019 M happened. I think we started working on that in, it was later than I wanted it to be, but I think it was January of 2019.
