I got the RN4081 / NJoy Npro at 7-11 because it was only $20, and I wanted to try eCigs. Best decision I ever made.
Since the first time the charging light went green, I haven't had an analog. I have, however, purchased about another $100 in parts, accessories, and
juice online to keep me
vaping.
My next quest is to order several sampler packs of flavored juices to try them out. So far, I have only used the stock NJoy menthol, and a Tobacco/Menthol juice I picked up locally. I find that after only a week, I'm already pretty sure I'm going to give up the Tobacco and/or menthol flavorings for something a little more "spicy" like cinnamon, peppermint, spearmint, etc.
I like the 4081 platform, and will probably stick with it for at least the immediate future, until I decide to make a few of my own PV's from scratch. I'm an Electronics Technician by trade, and have some "wild" ideas to try out, most likely followed by small explosions and fires. I'll post about anything that doesn't burn my house down.
I'm all about DIY, and once I get home (I'm working/living on a ship until March), the game shall be on.
