Hey Ferret, welcome to ECF!
As far as all of the 21st century ecigs go... I would just stay away in general. There are two different companies that go by similar names: 21st century smoke; and 21 century smoking. The latter they sell in my mall for absolutely ridiculous prices. I haven't seen one up close since last fall when I had a run in with the mall kiosk, but from memory it looks like some kind of knock off 510/808 with proprietary
threading. The 21st century smoke brand seems to be disposable gas station cheapos but I haven't had any experience with those ones. I suppose the disposables could be useful in an emergency since their only like $10. Either way, I would have to say you'd probably be happier in the end picking up an actual Joye 510 or Kr808d-1
You can get Kr808d-1 starter kits from
Vapor4life or a 510 starter kit from
Liberty Flights. Don't forget to click the 20% off button on the top left corner of Liberty flights site! You can get the same gear from other suppliers like litecigusa.net among others but I have personally had great experiences purchasing from both of the suppliers I linked.
What gear are you currently using?
If you're cool with your
ecig not looking like a real cig, I would suggest a 510 eGo or 510 Riva. Both use a standard 510 connection but have a bigger battery than the standard 510. I've been using my eGo for almost a month now and I love it. I only drain about a full battery a day (most kits come with 2
batteries), and I hit this thing pretty regularly. I bought my girl an 808, she smoked less frequently than I did and really wanted something that looked like a cig, so the traditional look and the shorter life on the 808 battery is perfect for her.
Dive in and research as much as you can to find out what's going to work out the best for you. Everyone has different needs.
