thought I spelled it wrong,huh? Didn't notice until I started messing with it. Has impedance printed them, tanks don't say Vivi Nova but look the same, thought I was getting Vivi. Guess I paid Viva prices for Vivi looking stuff though. The tank has 4 wicks hanging in it these replacements have one thicker looking wick. Any difference in vape/wicking action? Who needs the logo.Anyone else ever notice this?
