I have not used one, but I do have cobra which is also a genesis style atomizer. You use a mesh wick that you role and oxidize then wrap the coil around that. The juice goes from the tank (so no dripping) up the mesh wick due to capillary action (with the holes being close enough, many use #400 and there is another thread showing #500 wicks better.)
At this time I am using 400, had ordered that before reading the thread I mentioned, and it works really well but will probably order 500 some time down the road.
