Well I'm new to this vaping thing and am a proud owner of a njoy ecig. Typically I research first, but on impulse bought this at the gas station instead of a pack of smokes. It was all they had, there were no alternatives. A week later, smoke free, I want to see this company and form factor of ecig survive. I'm just surprised that this 4081 section is so dead. Lets bring it back...if you still love your 4081 lets hear it! I love that this thing got me off of smokes, it satisfies me and replacements are readily available. I've even been refilling cartos..sorry njoy, yours are overpriced, that took 0 research
