Hello all. I have been using a epower 14650 for over a year (smoke free). In that time I have gone through about 6 switches. All but one of them was pretty short lived. I need another, and after buying one from crystal clear that didn't work more than a day, I'm not sure what to do. It looks like a lot less places are carrying this vaporizer. Is it discontinued now? I like the 14650 size and would like to keep using my charger and batteries etc... What are my options? Are there decent switches for these out there? Is the vivi nova the same thing with a different cart/tank?
