Yes, absolutely. I mean I think this is an important question, and I get it on every earnings call. Basically, the way the battery industry works is a little bit different from semiconductor industry. We first sampled standard-sized batteries and like rectangular batteries that we believe is the right size, not exact size, but right size in terms of capacity. And the customers test them and they give us a series of tests that they would like to do, and we do those, and we do that in our factory to make sure that it passes everything and we give it to them. And they test it for a few months typically. And then they give us the exact dimensions of the battery. And they -- one customer has given it to us right now. And then we make the battery to that dimension, then they're going to take it, put it into their phone, and then they're going to do the cycle life test. As I mentioned, 1,000 cycles, and that takes months to test, and that's what they do. And then as TJ mentioned, there's a lot of tests like crush test, drop test and so on that they do, and that takes some time. And then what they do is, typically a particular model of a phone has multiple SKUs that they launch into different parts of the world, some launch in India, some launch in Europe, some launch in U.S. and so on. And then they take a new supplier like us and put us in one SKU and start with that and make sure that they feel comfortable introducing new technology. Then very quickly, it's going to second SKU and a third SKU in that model. Then once we are qualified and we are a valid supplier, very quickly, it moves into multiple models, right? And again, this is not that different with any other supplier. I know that Micron, same thing, we produced the UFS chips, got into SKU, then few SKUs, multiple SKUs before you know it. Finally, sometime later, we're shipping millions, right? And that's exactly what I expect should happen in this case. So we are in the middle of that with one customer. Now we've gotten a lot of interest after we launched the AI-1 platform launch, because now we have the technology. By the way, I don't think people quite realize, I think TJ wrote in the AI-1 press release, the amount of complex R&D work we had to do to take a 100% active silicon anode, put it under pressure, put it under the temperature stress and for the first time get a 900 watt hours per liter with 3C fast charge and 1,000 cycles and storage at high temperatures and work across temperature range. It has never been done before with 100% active silicon. So as soon as we launched that, I got a lot of requests from many customers. And in a couple of weeks, I'm going to be back in Asia. and we will sample this to other customers, and the same process will happen. They will test this battery, then they'll give us the exact dimensions that they need, then we're going to test them internally. We'll go to put them in the phone and then we expect the production to happen next year. That's the same process. And the second time around, it will be much faster because we are a valid supplier now. We're not the [indiscernible] supplier. But the first one takes some time.
