Oooh! That clears it up. Ok. See, I was imagining you could fill those from the top or bottom since the both come off. That eases my mind way more then.
OK so, now the evod glass comes with a dual coil setup and I'm running 2.2ohm singles right now. I don't want to have to waste my coils and I heard lots of ppl say dual coils use more power and juice, which is a big con. But then I heard I can use my single coils on it somehow, but also read I can't. Little confused there. Also, I do like the mpt2, and I would just go for that, but the evod glass just seems to be more durable looking due to the outer protection. But if I break my evod glass, can the glass be replaced like it can be on the mpt2?
