I have a VX2 so I'd like to add my own info which you may find helpful.
The atomizers are male, the batteries female. Thus making a shorter atomizer body and longer battery body. The atomizer has 2 breather holes in the screw thread side. There is no breather hole in the body. The wick inside the atomizer is larger than your standard 901. This results in more contact area to the cartridge filler. In short, the atomizer just works better and gives a good throat hit and lots of vapor! I should add that it took a good day or so before the atomizer starting performing to it's capabilities, but that is pretty much normal with atomizers.
The carts themselves fit nice and tight into the body, which I believe results in a better draw.
You also get a good 7-8 seconds before the cutoff on the battery, so if you like to take long draws you won't be disappointed.
Overall I like my VX2 so much I bought more batteries and atomizers from Shawn. I'm not going to say that it replaces my favorite e-cig of all, the 510, but it sure goes head to head with it. I basically rotate between my VX2 and 510 as I'm
vaping during the day.
And in case you are wondering, no, I'm not a shill for Shawn. I don't know the guy and I couldn't care less if anyone buys it as there is nothing in for me.
But this is a great unit and Shawn is on my short list of suppliers I depend on for quality products at good prices, as well as great customer service. And quite frankly, if that ever changes, I'll be the first to post about it in this forum!
