I guess this had better been posted elsewhere, but as a newbie this is the only place I am allowed to post 
I use a couple of eGo-T 900(?) mAh batteries with Boge 510 cartomizers, which I find to work fairly well apart from a bit messy filling, and I could wish for a longer usage period per filling/topping up.
I have noticed there are some dual coil Mega cartomizers out there, and I am curious to know what kind of experiences people have with these versus the Boge 510's.
