I got my ego but have been sick for a week,so today decided to check it out. From what I can gather I put juice in it until the filling is wet,but watch and not get in the center coil hole,right? Also everyone keeps mentioning the tanks and the dual cartomizers together,I dont have to use the tank and cartomizer on my ego do I? I thought just the cartomizer,My boyfriend has the tank and the all day cig and I hate the tanks,I cant top them off without making a horrible mess,and when trying to unscrew from the battery,I always make a mess.Any tips on this? Thanks for any and all help.
