Ok ive had this little guy about a month now, and he's still kicking. I still get clouds of smoke and the flavoring is still good. Obviously the cartridges havnt lasted as long as the Pen style but the do good for being a smaller version. The atomizer has been GREAT, of course ive been babying the thing ever since I read how touchy they are hahaha. And as far as the batteries, I get about 4-5 hours out of one. I mean I usually have the cig with me at all times and catch myself puffing on it quite a bit so its expected. All in all im pretty impressed. Just wish they would have a battery that would last a couple days instead of hours. Thanks everyone and ill answer any questions if anyone has them.
