I have an 18650 sigelei Chi-U that im currently using a Tobh Atty dripper with a 24 gu 6/5 wrap on rayon. I havent picked up an ohm reader yet but last i was at a vape store it read .27. I love the set up but am having a hard time finding a free hand to drip with at work and driving. What is a good rebuildable tank atomizer that i can use on my set up while i only have one free hand?
