Seriously pump the brakes and read up on this stuff before jumping into rebuildables blind.Its dangerous if you don't know what you're doing.Safety safety safety! Everyone new to vaping wants to blow clouds,there's nothing wrong with it but focus on getting off analogs first and then get into RDA's & RTA's if you want to.Its not worth blowing your hand off or half of your face.Sorry to be so forward about it but its the truth.
