thanks for the help,
i watched some youtube vids, tips n tricks n stuff. dont know why i didn't do that days ago. nvm.
i learnt the piece that the coil sits in is ceramic, explains why i trashed mine so easily :redface:
i have got the 4ml vaping ok now, think it could be better but i have been able to lower the voltage from what i was having it set at b4 and still get more taste. better for the battery too i spose ?
not so good with the 2.5ml, prob only need to develop 'the nack' with these things.
tnx again
