I went 5 months on a kanger mini pro tank 2 with a e go twist battery started rebuilding coils for it after a month or two of vaping.
Making the tiny coils got me ready to start making coils in a RDA (dripper) but found I didn't like my RDA till I took it sub ohm. on a mech.
Also found sub ohm eats e juice like crazy and 6mg juice hits like 18 mg I still use my mini pro tank on my mech.
So if you want to spend 10- 30 min making coils in a RDA's are awesome!
you do have to add drops every 5-15 puffs and if you don't use most of the juice up in the RDA it can leak out the air holes
Tanks you can just buy coils and change in a few sec. and they don't leak. great when your driving or running around.
Like I said i use both though when I go from my RDA to my pro tank I hate the feel of the tight air flow at first always feel like its clogged lol!
Hope what I said helps
