So, the first week I had my ProVari I was blown away with it's performance. Now it seems no matter if I have the unit set to 3.3 or 5.5 it burns the same. I would say it is closer to the 5.5 side (keep in mind this is when I use the same atomizer so I know it isn't a difference in ohm). I did have a slight juice overflow once, so I am trying the rinse method right now. Hopefully that'll work. Could this be anything else though?
