I agree on the 510. It's all I own (I have about 8 atomizers, 10
batteries, many cartridges). I love it.
I got mine from cignot.com, home of the 510 "no box" kit. Killer deal.
As they say on
their web site:
"Included in this kit is 2 complete Joye 510 cigarettes (2 atomizers and 2 batteries), 5 prefilled carts(Marlboro High), 1 AC charger. All that is missing is the big white outer box!"
All for $35!!!.
Imagine that: 2 complete, reliable 510's, probably the most popular model among ECF forum veterans and newbies alike (just my impression on that, but I'm pretty sure I'm right). Add to that cignot's justly deserved reputation for shipping stuff almost before you click "submit" on your order and, well, it's not hard to see why some of us would rather go back to analogs than shop anywhere else.
Don't forget to pick up some clean, pure Ecopure e-liquid while you're there!
