You're absolutely right about build quality, for both chipset board and the mod itself, and guarantees applied. But it has a price to be paid, *******Oops!, rDNA HAS replaceable battery....my bad!****
actually two: double price tag (under the special offer)
and just 1200 mAh battery capacity. And it is not replaceable under daily circumstances.
As always, we want all, we want it now, and we want it cheap (but not without quality)..... We want too much!.....
Once we return to firm ground, it's about compromises. The iStick was far from the ultimately device after knowing its flaws, but even after that for many it has a balanced compromise between desirable capabilities, mostly because its size, form factor and battery endurance. Then we ask for replaceable batteries, a well built 510 and real wattages... but below the $100 price tag. Someone saw the opportunity (actually, a lot of Chinese manufacturers, according to YouTube....

) and they are working against the clock to provide the new ultimate device, again, based on size and form factor.... and price tag.
This is becoming interesting. I do not know if it is better to watch it calmly seated with a good vape or just pulling something toward Christmas......you know, some PayPal account....
