I don't know how handy you are but check out this guys work.... worth looking at. But I do like my maps!!! http://www.e-cigarette-forum.com/forum/modders-forum/167225-best-3-tank-mod-youll-see-today.html
Unfortunately I don't have that option. It's gonna get shaken up, it's gonna go from vertical to side to upside down, I don't have the option to just set my PV down during daily activities or work. My handy little cig spot in my car is also horizontal, so it's gonna get set on its side. I know, it's a pain in the ..., but I don't think its too much to ask that I put a carto in my pocket and walk around with it without getting a mouthful of nicotine when I go to take a puff.
I'm getting about 3 hours out of the IKV gold v2 but the flavor's not as good as the Royal Ce2, but I'm about one more "gurgle" away from pitching the ce2's. I'll definitely try the ego tank system even though it's a little more than I'd like to spend on a trial and error product. I'd love to get a MAP but I'm very sick of having to unscrew, blow off, and wipe out just because I set the thing on its side, or it got shaken up in a pocket.
