I had the Vivi Nova some time in use, everything was okay. Evaporated quite good and tastes good so far. In an evaporator head splashed always a little hot but unevaporated liquid on the tongue, but it was bearable. With me also kokelte nothing, and the tank could evaporate completely empty. Is not great, that I know the tank is completely torn. The contracts of the threads in the middle of the tank. Lauter smaller and larger cracks. And it does not come from the turn too tight, but unfortunately by the damped Liquids. I never evaporate menthol, fruit etc. Pure, yet the tank is cracked. Even if this is a known issue, I think it's pretty weak. I buy me not the Liquid inversely to the evaporator, but rather yet. You could also tanks "tempering", ie heat treatment, then they would keep better. I now use the Kanger PROTANK II, which has a glass tank and works very well. He also looks high and is a bottom coil system in which the steam is not so warm arrives at the mouth. Incidentally, this Vivi Nova no original vision. In the original tank, the level indicator will stop the way with 2,8ml on, and that's also the maximum amount of liquid because the evaporation otherwise being "flooded" you fill on.
