Been wanting a coil master v3 for a while but just to lazy to order it on line. I was at a local vape shop getting a battery for my son whose in the hospital, while I was talking with the owner about my Reo I looked down and there it was and it was their last one...got it at a good price too. My coils are fine with the RM2 but I am just about to order the 0-16 and I want to be able to experiment with different diameters and the Gizmo just isn't up to it.
