Alright, so I think I'm finally ready to move up into the world of rebuildables and I'm thinking about getting this Kayfun because I've been getting really frustrated with my Protank/Aspire coils and tank systems. Now, I have a super basic knowledge about how these things work (basic meaning that I occasionally replace my wicks with cotton, I don't rebuild the coils or anything, just swap old wicks out until the coil gets super old and then I throw them out) but I was wondering what kind of resources everyone used to make this switch. Are there any really good resources (text posts, youtube videos, channels etc) I should check out to increase my knowledge on how to use these things before I dive in?
