Does anyone have the smok osub mini with no buttons etc to adjust the wattage etc? I am interested in getting one and trying it with t-18 tank or buying a nautilus mini to go with it. I want a mtl and the helmet nano tank that comessage with it seems to be more towards direct lung. Also, I am having a hard time finding it in the USA to order. If I order from the smok website, is it safe? I just like the size and that the whole cover that covers the USB port is the fire button. I have the tarot nano now, but I did not like the nautilus x tank and the t-18 tank doesn't look that good on the tarot nano as it is too tall. Any information would be appreciated.
