No prob :) the wick must be snug but not jammed in, also try cutting the wick tails at a 45 degree angle so there's a thinner piece of wick going into the juice channels.
Looks like you've too much wick in the one coil and too little in the other one but why don't you get the dual RBA for the smok? The RBA you're using is designed for a single coil.
As the title suggests i'm looking for replacement glass for my melo 2. I dropped it, it broke and now I'm sad. I dont use this tank often but it's nice to have around as it is simple and great for when I'm too busy to re-coil or re-wick.
if you use the single coil rba it's actually pretty economical.. the dual coil however is very thirsty! I've heard good things about the Griffin too but haven't tried it yet.
