This may be on here but have not found it. I just got the ego setup and everytime I fill the cartomizer I get a leak through the bottom. I leave the bottom cap on while filling but after filling I remove that to screw it onto the battery and there is a lot of liquid (lot being relative). I do not know if I am filling wrong, or if I have a defective cartomizer. I do not fill past the fill hole with the needle. Any ideas? thanks
