i got a vivi nova the other day at a vape shop in st.joseph mo and it is a 3.5 ml tank with a 2.5ohm coil head and 4 strands of silica wick. i went from a cartomizer tank system to this cause my cartomizer burned and i wasn't able to buy more cartos at the time. but with the vivi nova i have noticed after setting i pick it up vape on 3.1 volts and get a good hit but when i go to vape again i get a burnt taste every time i think it sucks at wicking. anyone else have this problem or a fix to the problem it is a good tank but i like to chain vape for a little bit lay it down for a while pick it up again and chain vape. to me the vivi nova dosen't like me chain vaping much but i do plan in the near future to rebuild the coil on the vivi nova but i dont' have the stuff right now to rebuild but mainly i want to know if anyone has this problem and maybe a possible way to fix it.
