I have a vivi nova V2 from another provider. No muted taste. The 2.4 Ohm rated has 2.5 Ohm, so thats OK. Amazing flavor right out the box. Much vapor, flash don´t know, using 40/60 VG/PG liquid with 0.6 nico. The best clearo tank I ever had right out of the box, no fiddling, easy to handle, big enough tank, cheap spares. If the V2.5 is still better....People, get some of these, they are great.
