I mentioned the "bumping" as it's a lot easier to upset a Geni coil than another style build. I took an Ihybrid pure to Disneyland in my wheelchair, I had to fiddle with the coil a few times when people would bump into me hard, or if my wife hit a big bump when pushing me with the mod in my pocket. I had the same problem with my ZAP when I went to a NASCAR race. It's not a huge deal, just something to be aware of, the Provari wouldn't fire, the Ihybrid fire switch would get hot, but both let me know they weren't happy!
That's something else I learned with the Pure, keep your builds above .7 ohms, not sure why, but the fire switch gets rather warm, rather quick with anything lower.
