True.... It comes with two rebuild-able RDA's which you have to match the coil builds, I do understand that, I was wondering if the double adapter on the top may fit on other tanks, if anyone had seen them with an alternate config.
Well I was thinking of putting dual Kangers on it, or even a pair of 30mm Kayfuns I have at home, but looks like the bridge is made for a bigger form of drip tip..
Oh well there is always the Chain Smoker, but I wish I could find me a Triton HELLS GATE MOD
Here is a double black Kayfun 30mm holds about 35ml, and if you look closely you can see the high temp silicone extension tube I made for the added lenght, it attaches to a Big Russian drip tip which actually fits perfectly up into the cap...
