I just got my ego twist today, I'm using a mini nova, and in about 3 hours, I've used almost 2 ml of juice already. I don't feel like I'm using it any more than I did my other PV, but I don't remember using this much juice before. Am I just imagining this, or are these novas just juice hogs. Maybe it's just because I can see the juice and the little scale on the tank and it's throwing me off when I can actually see the juice level going down.
