Hiya, I've searched this site for an answer and I'm sure it is buried somewhere, but I need help... When I started vaping my first couple PVs were 2-piece styles, just attach the cartomizer and go on my merry way. But then I got curious about a Riva 901 and bought that, which is the 3-piece style. The instruction booklet is dismal. So now I come to you. Knowing nothing about the prep and use of an atomizer... it came in it's little packet and was a little wet, so I just wiped off the sides. Later I saw someone mention blowing out primer. Oh my... was I supposed to do something like that before using it the first time? Am I going to die now cuz I used it with primer in it? (just kidding but was that a dumb thing to do?) I've seen people talk about the atty bridge, and now I see it, but don't know what that means to me. I'm just feeling super stupid about this and ready to chuck it and go back to cartos, but don't want to waste this money without giving it a shot. And I've watched a ton of videos and haven't found any that cover this. Thanks for any advise.
