Hi Everyone - I am new to Vapor4Life. A day ago I received my EGO kit and two 6ml tanks. (my friend told me what to order). I watched the video to fill the tanks and did so. The first tank worked for about 10 mins and quit. The second tank worked on one battery but not the other. I just charged both batteries and now the one working tank doesn't work on either battery. The large black cartomizers that came with the kit work just fine. Its just the tanks. I am at a total loss. How do these tanks work for a short time then just stop? I looked at other posts in the forum - but can't see to make sense of what might be the problem.
