Yes, it’s a good question. It’s a two-fold answer. There is two points to make here. We started this UL testing back in early 2015 and went through it for the first time with our initial product, and there is a lot involved. There is just more than you believe. On the surface, it’s really testing for durability and safety of the packs. So, we felt that was really important with lithium and being new, and it actually took us forever because we had to go out and get all these third-parties testing. So, you had to reserve space and time and facilities in Texas and elsewhere, and UL had to – come in and out all the time. So, over the past 6 years, we have UL-ed all our packs, our first generation. Now, we just went through this new platform. So, we developed a lot of experience and confidence by UL and what we can do. So, along that journey, we said, hey, let’s buy some of this equipment because you know what, we could use it for just internally developing our products. Shake test, vibe test, high-temp test, low-temp test, durability and so forth. So, we bought that equipment, and that’s an enabler to accelerating the timeline it takes to develop products internally to – and any of the elements of that. Then secondly, UL testing is not cheap. We spend hundreds and thousands of dollars on that. And being able to do that test internally where they just – they have to monitor series of tests as part of their requirement and compliance. So, they can do it either on-site, on Zoom or we can tape it and give it to them. So, we would really – and we are not sending anything to Texas and other places for third-party testing. So, it has a benefit with many aspects to us, both financially cost-wise and time-wise.
