Looks like it may be along the same styling as a Kayfun/Russian/Rocket, as far as bottom coil, tank in middle and chimney thru the center to the drip tip, but it has double the wicking channels and they are far wider than on a Kayfun or clone. Looking at a video review of one right now and from the build of the threads and the hefty size of the o-rings it may be even more leak resistant than a Kayfun. Watching the guy on video fill it, it seems to actually create a vacuum so it does look very leak resistant
For the price of the Aqua, however, you could have almost 10 Kayfun clones. That said, if you want the absolute best vape available in any tank system, the Aqua would fit the bill nicely. Nothing is better. Yet.
