Just wanted to give everyone a heads up on an amazing set up on the mini. I got some 1.25 dual coil pre punched carto the other day from madvapes on a whim. I put it in a tank and intended on using it on my Precise. Well the flange on it blocked all the air flow and I was at a loss as to what to do with it. I put a 510 extender on it and put it on my REO mini. It was amazing! So I took it out of the tank and put it directly on the mini and it goes on great with no air flow issues even with the flange. I put an AW black protected battery in to better handle the load and a drip shield to cover the tiny hole. I have many VV mods and this is as good or better. This is a must try on any REO!
