For now I'm pleased with the performance. Every now and then the contact screw walks down a little and doesn't make contact with my atty but i just unscrew a 1/4 turn and good to go. I really like how much smaller it is than the MVP i was using. I thought i was gonna drip at home and use my tank while driving but after getting the airflow from my Plume Veil, i can't go back to my tank! So i just drip at Red lights or drive with my knee!!
Currently I'm running a single coil .62ohm, 4.34v, 30w using cottton wick. And I'm dripping Blue Dog competition Tooti Fruiti. PG free 96% vg.
Oh; the coupor mini has adjustable center pin; that's good.
