So I've tried out my kit and I have a few comments/complaints/questions.
1.) When charging a battery in the PCC, the 4 PCC indicator lights remain ON while the eroll battery is charging (which also has a blue light that lights up when a battery is being charged). Can anyone tell me why on earth, the PCC 4 lights need to remain on, while a eroll battery is charging? I can understand the blue light (that's for the eroll battery itself) but why on earth does the PCC set of 4 white lights need to be on? This just seems like a battery waste to me for the PCC charger. But what I do know? I'm currently still charging my eroll battery in the device right now, so I can't tell you if all of the lights go out when the eroll battery is charged, or if only the blue led light goes out. I will update in a few... UPDATE: When the eroll battery is fully charged, both sets of lights on the PCC go out. I still don't know why the PCC lights need to be on when charging an eroll battery though. If anyone has ideas, please chime in!
2.) I wish the blue LED light at the end of the eroll battery lit up ENTIRELY (including the edges) like Blu batteries did. When I'm vaping, I want to see the light glow blue and you can't, unless your watching yourself in a mirror, or in a dark room, where you can see the light glow onto other surfaces as you drag on it. But actually looking at the end of the device while you draw on it, you won't see the light glow blue...this is a big disappointment to me. In vids I watched of this thing, it seemed that the vapor COULD see the light as well, when they dragged on it.
3.) Regarding leaking, I have 70VG in my carto, there is no leaking (so far)! I haven't tried 50/50 yet but I will on my next fill. I'm only using 3MG juice (no nic salts) and I can still feel a slight buzz when taking a drag on it. So don't think you need nic salts or some crazy high nic content to use this, you don't!
