Yes, that's the setup I have, you punch a hole in the plastic tank when you insert it the first time.
I don't think there's anything actually leaking though. The tip is clean. It seems to be the vapour itself. After I exhale, I get a definite sticky feeling on my lips.
I kind of like the 510T, because it's compact and I like not having to press a button. But I'll do some more research - maybe I'd be better off with something else. I still haven't quite got a grip on all the tech, cartos, clearos, coils, etc...
i see. im glad its not leaking on you then. and i understand you wanting the compact no button press type of e cig. how ever my use of variable voltage on my device allows me to set to a warm or cool vape. i have never got sticky lips tho. maybe when you take a puff take a slower longer inhale without so much suction. sucking on it real hard will not give anymore vaper. unlike a real cig. vaping can be abit slower/different cause you have to kinda w8t for the device to give you the vape. big reason why i like variable voltage/wattage and a button
