I think you're right because they say the NCig lasts for about as long as a pack to a pack and a half and the NPro only for like 10 cigs. Frankly it seems like less than that to me but, oh well. I wouldn't mind trying the NCig and see how it works out.
No, I just have the NPro, I think the difference is the cartridges, the NJoy standard has the flat tip thing and lasts a bit longer and the NPro is just like a regular cigarette.
thanks, i have a smoking everywgere cig which also looks like a real cig. but i think the design allows for the e-liquid to dry much quicker than the njoy. either that or the flat tip allows for a meatyer drag over the round cigarette type mouth piece.
