If you are going to buy premade juice vs DIA, use the X4 coils and avoid the T8. juice consumption is incredibly bad with the 8 coil head and the 6 isn't much better. About 2x the two different 4 coil heads and that is only running the T8 @ 60w and the X4 @ 45w.
I can blow thru 20-30ml a day with the T8 and only use 5-10ml with the X4. HUGE difference.
Whoa!
I make my own liquid, I use RBAs and make my own coils. Making liquid is pretty easy, software gives you the amount of liquids to add for the correct PG, VG and nicotine, then you add the right amount of flavor. There is a bit more to coil making. Take it slow and learn as you go, it's become a hobby for me.
Is there any place you would recommend for DIY stuff? As well as a software. It sounds like it can be a cheaper and more enjoyable alternative to consistently buying.
