Thanks everyone. Leaking is intermittent. Must be my atrocious wicking :-D. Will just have to keep practising. I think also possibly need to re-wick more often. If I leave it longer than a week then the leaking seems to start. I've been using firebolt - 1/2 of one piece.
Any advice on wicking? I've tried two methods - cutting ends of cotton upwards eg. and cutting normally . The goddam thing leaks after about a week. So I should re-wick every 3 days?
Only been using since yesterday. Impressed so far but using a coffee juice which I don't enjoy that much. Will change to a tobacco. Impressed how small and light it is. Perfect for when I don't want to carry a heavier bigger mod. Also the juice I'm using is 3mg. 6 or 12 would be better...
