I have pre-order this mod, and can't wait to receive mine. This will be my first rebuildable mod. I'm currently using a Kangertech suboxmini. I love the look and style of this mod, but can anyone tell me if I will be able to buy prebuilt coils for this thing? and can I also use different tanks on this mod? Lastly, I've been told that this will start shipping by the end of December. Does anyone have any information regarding on when we will be receiving them? I'm anxiously waiting.
