 When did the Dynaquil come out? This video came out February 7th, 2019. There was certainly a demand and a growing demand for a better alternative to use concentrates in our devices. I started to think, okay, how could we do this and do it in a way that's more in keeping with who we are and what we represent as a company. So after drawing a few things up in CAD and coming up with a few variations in terms of dimensions, it came down to coming up with an interesting pattern. This is our first go, this piece here. It's kind of almost like a pattern that is V's of varying different degrees to try and make it a little bit more interesting and also make it a little bit easier to roll up because I was concerned that the material itself would be a little bit too stiff to roll into a nice cylinder without a specific jig or fixture to hold it. It ended up rolling up okay, but it wasn't great and the diameter was a little bit off. So the initial speculation in terms of how we could do it, I'm sure that if I would use a more purpose-made fixture with higher pressure rollers, etc., we could probably wind it a little bit tighter, but that wasn't the point. In round two, we increased the porosity a little bit, shortened it up a little bit to make it a little bit easier to roll and got something that was a little bit better. Finally round three, this one, it was pretty much the one we're going to go with. The way the Dyna Coil pretty much looks today if you were to unroll it, which I don't recommend doing that because they're kind of tough to roll back up. So we roll them for you to make sure that they're the right size, the right dimension, and that they look nice. In general, the overall development from inception to yep, let's make more of these, I think this product will sell, was probably about nine and a half to ten months. I think it served its purpose pretty good, but we've been able to identify a few opportunities for improvements.
