I have been using the Ego-T e-cig to stop smoking fags, but found initially that the liquid leaked into the mouthpiece and was unpleasant at times. The solution I have found to this problem is to have a stash of tanks and only use 1 per day. After a few days I wash them all out in warm water and leave them to dry on the window sill and keep re-using them, seems to have solved the problem, I certainly don't get leaky tanks anymore. If anyone has any other tips for keeping the tanks leak-free I would love to hear.
