Got a couple of adapters that allow aspire dual coils to be used on pro tanks, I have pro 1@2. They work very well as I like the warm vape I get from aspire coils. There is a little plastic thing that fits on the center tube to seal the liquid from going down the center tube. Just for kicks I left the plastic thingy off and just connected the coil with adapter to the pro tank. I am getting an even better vape this way, and so far no gurgles or flooding. Anybody else tried this?--Hawk
