Hey Grimmer,
So far the vapor is pretty damn good...you can use them on a 510 battery but might have trouble on other 510 mods because the connector is recessed up inside the tube a bit. I had to use a couple adapters to get one on my original GGTS.
I should have them on the site in a few days.
Is the cone made of metal or plastic? either way shouldn't be a problem. maybe I could just cut the excess over lap so the 510 threads could easily work on any device with a 510 connection.
Could this be done without hurting the cartomizer?
