I'm going to line up with the people wondering how this thing is supposed to work and whether it will be any good at all. I just passed my 4 yr anniversary for vaping and in that time I've been MTL at least 95% of the time. I wasted a lot of money on atties that were claimed to be the new best thing.
First, a great MTL atty has to have everything working together from one end to another. Many makers have arranged for a small air flow, small chimney, reduced chamber, etc. I have yet to find a great atty with just one or two of those parts. I've even had a few that had all the right parts but failed miserably because the vapor was being asked to do things it didn't want to do. I won't bore people by getting into airflow management, velocity, atomization, or keeping the flavor traveling with the air stream - you know, Real Science stuff. But a reduced chimney won't produce a good MTL vape if a lot of things haven't gone right before it gets there.
So in light of all that, the chamber looks huge for MTL. Also, I'm not sure why you would want to raise the deck way off the bottom of the tank. As for emptying the tank, though some have mentioned that wicks will be run all the way to the bottom none of the photos so far show them below the build deck. There are more things that make me wonder, but this is too long already.
EVERY atty that I truly enjoy looks to have lots of thought put into the design - and I'm not talking about marketing thought or whether it looks right on today's mods. A Kabuki is legendary for very good reason. It's the best there is for premade coil mtl vaping, though the Nautilus 2/ .7 coil came amazingly close. For rebuildables, I enjoy (in order) the Narta, Narba, and Narda. I have 6 or 7 mods going all the time and a Hurricane is always in use. A ByKA, Cloud One, Kayfuns, and a Taifun get used from time to time. The items I named are sort of unicorns for a lot of people and I was lucky to get them. But the reason they're unicorns is because they are so much better.
Anyhow, I'd like to see the siren clone (I keed, I keed) join the ranks of the atties MTL vapers rave about. But I'm going to wait and see, and certainly won't be surprised if the vaping market is once again led astray by more sizzle than steak.
