I just recently entered the realm of RDAs and I'm loving it! In fact, I'm blowing huge clouds off my tugboat as I write this. I am concerned about one thing. It seems like my positive post is getting hot. It's not glowing red like some people I've heard about, but it seems to be vaporizing liquid and is changing color a little. The screw started out silver like the negatives and now looks kind of brass. By buddy said my ohm's are too low, but I'm at .46. I don't know if this is normal. Like I said, I'm happily vaping right now and maybe I should just go with it?
