I've only been vaping for a short amount of time now But with all my newly aquired hobbies I love variety. So far I've used a nebula and a janty 510 and I must say I really love the 510. the nebula is very kind to me as well and i love the super easy draw but i want to step up to a high voltage device. From what I've seen in reviews (grimmren, doctorvapor,phee) these are some awesome devices. Although I have yet to find any remarks on the draw of the deices though maybe this has to do more with the atomizers. Are there multiple styles of 510? Mine has 2 holes and I find the draw a bit stiff (I'm used to nonfiltered analogs and find smoking anything with a filter to be insanely hard to draw on...started dripping for just that reason.) if anyone could give me some clarification on this I'd really love some feedback. If you have anything else to add aout either devices i'd love to hear the remarks too
