I hooked up the dual coil tank that comes with the OMG VV mod. The tank with Titan manual hit's like a real cigarette to me. In my opinion it beats the 1 Vapor4Life cart I have been using.
The tank has lot's of vapor with a nice throat hit.
I will say this, I have gotten ton's of use out of that one Vapor4Life cart. It has far exceeded expectations on what I have read about average cart life expectancy.
