I too have had some hideously leaking CE5's, they were poorly made cheap tat, so I binned em and put it down to experience.
i can highly recommend the innoclear iclear 16's, essentially the same as Ce5 but with a dual coil, they are very well made and also rebuildable. I haven't had a single leak from mine
