I have had my Ego-T since August. Last month I bought a Ce4 clearomizer and it quit on me two weeks later - about 4 hours after I bought a 2nd one. I didn't use the new one and was able - today - to exchange it for a Ce5 that lets you replace the insides if it "craps" out on you. After I finished the cart that I was already using, I got out the new one, attached it to the battery, filled it up, turned it on, and tried to use it... Here's where the problem is... There isn't any airflow. If I take it off of the battery to check airflow through the Ce5, it flows the way it should when it's attached to the battery. I can't figure out what could be blocking the airflow. I sent a text to the guy I get my equipment from and he said it could be clogged, but he hasn't had any problems with these working with Ego-T batteries before. Help, please!! Any ideas??
