Hey zaraza,
I bought my E-Cig+Atomizer+Cartriges from
www.absolutelyecigs.com because I heard that other people had good success with them. I bought the M401 starter kit, used Paypal. Shipping wasn't cheap, it came from direct from China via Chongqing to Shanghai, then through Vancouver to Ottawa... But everything arriving intact and in good order...
The E-liquid, the liquid that you use to refill the cartridges, I bought at
http://www.totallywicked-eliquid.com/, again for no other reason that I heard some other people have had good success with them. Again used Paypal.
But there are tons of places out there to buy both the cigarette+accessories and the E Liquid, just do a Google search for E Cigarette, E Liquid, etc...
As I understand it, there not in American and Canadian RETAIL stores yet, because they are so new that the government Health agencies haven't yet had time to grapple with and classify them.
Here's my kit:
White batteries with Orange LED that lights up when smoked... The black battery has a blue LED when smoked.
30ml bottle Super High strength Coconut flavor E liquid with dropper.
The battery charger has a USB plug so you can plug it into your computer.
Couple of cartriges... They have sort of a soft fabric mesh inside that absorbs and holds the liquid.
and an Atomizer, that thing at the bottom that looks like a 22 shell with a bit of steel wool... That's what heats up and turns the liquid into vapor.
Cartridges are very similar in size to a normal cigarette filter... In fact, when assembled, the E Cig looks remarkably similar, just a lot heavier then a normal Cig... I haven't quite figured out yet how long a fully filled cartridge lasts... It really depends. I've noticed they do less well in the cold, the liquid doesn't seem to flow... So you can end up with a half full cartridge that doesn't smoke because half of the liquid is "Stuck"... I solve the problem by taking with me a couple of topped-off cartridges to swap out at the first one goes weaker...
Once back inside at room temperature, I'm amazed at how long they last... Maybe 1 cartridge last as long as 5-10 normal cigarettes...
But ya, I've your interested, check out
Youtube, you'll find tons of people explaining their own kit, where they got it, how to clean it, how long they last, etc...
Good Luck!
