Today i recieved a vivi nova in the mail, and a complete waste of money. I wanted to switch from cartos because the seem to loose flavor extremely fast but last forever. So i had my hopes up for the VIVI and totally let down, Ive tried several mods here on ecf and none seem to work. Is there any suggestions to the best delivery system aside from dripping ? I have Boge SR and Volcano carts and both work great at first then loose flavor after about 2 -3 days of vaping
