Blatantly rips off the Boreas design shamelessly, then doesn't deliver nearly as many features. It seems really 'bland', the only upside is being bigger. Other than taking a 25mm design to 30mm, they've showed zero innovation, they've actually went back because it has no juice flow control at all.
I own one, and, other than holding more juice, having more air (too much, to the point of just inhaling from your mouth) and having a bigger deck (which the chamber handicaps slightly, like the VCMT) it does nothing better. Machining quality is meh at best, the lack of spares is in your face for the price, the price is a joke and the lack of JFC is just a why? sort of scenario. The flavor production isn't even close to that of the Boreas.
Unless you just hated the Boreas because it wouldn't fit your 4mm 10 wrap fused claptons and didn't hold up to your 4S 16.8V Lipo box at .15 ohms, there's zero reason to buy this. It does nothing the Boreas does better, it just has the benefits you would get out of making ANY device bigger, nothing more. If this had functional JFC and maybe a better fit and finish, I could see it competing with the Boreas at around the $30-40 mark, but as-is at $60, it's a purchase best avoided.
The kind of crowd this thing caters to isn't the type that runs with RTA's. This is the kind of device people who like to throw 600W+ on the daily buy to screw onto their triple series, 3S/4S unregulated lipo boxes and 300W regulated mods. There's 28.5-30mm+ RDA's that cater to this style of vaping MUCH better than this thing does, so its existence is a bit of an oxymoron as people who like to vape this way generally wouldn't like the limitations of an 18mm deck and the fact that it's a tank.
