I sub ohm with the Alien and the cloud beast. But I do like the nautilus because I occasionally like to take cigarette hits. I am looking for the best device for using that tank with (I have the Nautilus with the armor instead of the glass too). I don't want Isticks (40W) because they are too cheap and one broke on me. A small good device no matter the cost is what I am looking for. I had the Target mini but the tank would wobble when fully tightened. Can you please advise me as to what good and small device is a good idea.
