I vape multiple flavors of juice all day. I have 3 tanks of liquid and my Reo with another flavor. I'd consider the liquid I have in my Reo (rip tide from pink spot vapors) an all day vape but I'm always carrying around my evic with 3 tanks and my Reo. I'm not concerned about battery life as the battery on my evic would last almost 2 days of just vaping that all day. Thoughts!?!?!?
