Hello fellow vapers! I'm new here and also new to vaping, so please forgive me for not being on spec with the terminology As a newby, I've been introduced to vaping with the Joytech Penguin, using 0.6ohm coils. I've had some problems with leakage which seem to be rectified now (operator error) and 70-30 juice (Australian) which has been really good. However, I've recently tried a new juice, purely because I like the flavor and am having problems with it burning out the coil. I think it is a 60-40. After a quick read through the forum, I'm thinking that this mix might not be suitable for those coils? Can any of you experienced vapers recommend a coil which might be better suited or otherwise advise me, please?
