My only problem with the o-ring is that it is little thick for my atomizer (Protank 2) and I have to really tighten the screw. I plan to sand the o-ring down a small amount to adjust this.
I get very good contact. Although I haven't measured anything, it hits about the same as my Nemesis clone.
A friend of mine replaced his switch connector pin with a piece of 110v copper house wire.
"what i did though is i cut the wire about an inch long and chucked it up in a dremel and polished it with mothers mag polish, then measured and cut it and smoothed the edges...looks like a factory pin..LOL...hits much better also."
