I like helping new vapers. I was one once and I keep in mind what it was like when I first started . All these sayings and terms we use were very daunting to me. I bought what seemed at the time a big complicated vapouriser called a Lavatube mini but I never used it for months as I didn't see the point because my slim ego style ecigs did the job. I also saw complicated juice tanks which they called Genesis so I bought a couple, watched a YouTube tutorial and built a coil which looked like a 4yr old had made. So I went back to easier tanks which has ready made coils in them which was the safest thing to do I think. But that direction can become expensive. And so over the course of time as my interest grew I realised that the ego batteries didn't give out enough power and died too soon and that having a tube or box where I can carry a spare battery was much more convenient. Same with juice tank coils and wicks. One day I followed exactly a YouTube video by GrimmGreen making his own coil and mine then came out perfectly and I haven't looked back. I also make my own juice 99% of the time.
