I have ce5 with wick on top. I have dropped it a couple time, when it hits a hard surface it will not work. I thought the coils were breaking, so I would screw in a new wick, but it doesn't work unless I replace the whole base. What is breaking in the base ? can I fix them ? It has happened 3 times now. I was worried the battery would break, but the only thing that fixes it ,is replacing the base.
