I believe that Joye makes the Janty product. Joye is a manufacturer and you will see their product offered at many locations.
I started my husband with 18mg even though he was a heavy smoker. For him it wasn't the level of nicotine as much as the inhalation/oral fixation. He's down to about 8mg and doesn't even seem to notice the difference. I mix our juice as needed and it's VG for high vapor.
As for flavors, we mostly use the coffee flavor I get from Juicy Liquid. Never really bothered with a tobacco flavor, although I do like the RY4 on occasion. There are so many flavors out there. Maybe find a juice starter pack with a few real small bottles. Nothing worse than trying a flavor, finding out you hate it and having a huge bottle of it left.
Remember there is a learning curve to vaping. Maybe consider a disposable to see if you can make the adjustment. If that goes well, I would go straight to one of the battery mods. It's so much easier to charge batteries once a day or once every two days.
Ive tried an e-cig a couple times before and I think I can get use to it. Someone on another board was tellin me that the RY4 was a good liquid.
If I order the Joye eGo kit from cig-not.com it comes with pre filled carts. Should I buy extra carts so I can put my own liquid in it?
