I have this kit and the CE4 leaks out the bottom on to the battery connections, i have a second CE4 and it does the same thing. i just got a glass tank from highdesertecig.com that came with 2 Smoktech DCT LR cartomizers and there is no problem with leaking. is this something normal with the CE4's? is there something i can do to stop the leaking onto the battery? am i doing anything wrong?
