Bottom line is, if you like direct dripping on a 2.1 -2.2 ohm atty using a 3.2v tornado, then you'll be happy with this. This is new technology and everyone loves toys, but this is simply replacing the bottle that we have to carry around when dripping, which makes it safer during driving. Also, you will still need to carry a few extra filled carts if you vape even moderately. I'm hoping their next upgrade will include 2ml tanks, that will still fit in V1 or V2 atties, but so far...I don't think anyone in the US has any V2 atties.
I like it, i really do, but I like it better on my 3.7v device using a 14500 battery. I posted a picture above. I used 2 adapters and I have it sitting on top of my box mod, there is about half inch of space between the atty cone and top of box but it hits a lot nice at 3.7 than 3.4-3.2v.
IT's a great set and go device when you need nicotine...People get caught up thinking that they need lower ohms to get more nicotine, which isnt true...you're still getting the same amount (in my case 24mg/ml of nicotine).. The ohms in the atty simply make the juice warmer and create more vapor, but it wont produce more nicotine for you
