I ordered the 510 as well from rocky mountain vapor an got it 2 days ago (the shipping was super fast). It's been a weird transition to this thing - I was super excited and now I'm not so sure. I'm definitely not giving up but it feels so bizarre to carry it around. I do feel like I made a good choice, I think you will too DP.
how serious of an issue is this? I haven't seen anything about this posted in other forums, and i'm afraid to put it in my purse. What kind of metal must it not contact? How much of a barrier must be between them?
the highest concentration i've even heard of is 36 mg
