I have been using a 510 with a manual switch for a little over a week now and I have to admit that the vapor production is not nearly as much as on my RN4072. The 510 gives more consistent draws which I'm sure is because of the manual switch, but as far as vapor production, I like the RN4072 much better. I don't know if this makes a difference but I don't use carts in either one. I just drip.
I have a question about the 510, though. I noticed some hairs coming out of the side of the atomizer. We have cats in our house so at first I thought they were cat hairs that got stuck and tried to pull them out. Then I realized they were part of the atomizer. Should I pull these out? Should I "tuck them back in" to the bridge or just leave them alone?
