I didn't want to link to the website because I didn't want to be accussed of advertising for them
But I got it from a smoke shop and the here is the product page from the company that makes it:
MaxxVapor Elite Starter Kit in Black
I did get it for cheaper than the price listed there

.
The main thing that's been surprising me about it is how quickly I'm going through e-liquid, the website and sales people made it sound like the eliquid last so long because a little bit of it goes a long way. Well unless I'm doing something extremely wrong, I'm burning through. I've used half 10mL bottle in 3 days. And maybe I had the wrong idea but I thought it was suppose to last a lot longer than that.
What I've been doing is putting 4 or so drops right on the atomizer and then topping off the cart until it just barely pools on the top. And that last me for about half of a good vap session and I have to refill.
So if this a "510" I can buy 510 compatible accessories from anywhere and not be tied down to that one company that sold me the actual e-cig.
