I have an MPV 2.0 that I use in conjunction with a PT3. The PT3 is a new tank for me that I got mainly for the 2.5 ML capacity. It seemed like a nice upgrade from my PT2 mini. It seems as though I am going through juice a lot faster with this new set up and I cannot understand why. Now I know that it is a dual coil set up and I know that this typically goes through juice a little faster but, I did not think it would be this extreme. I have mt PV set to 4.0 V and I am strictly using 50/50 juice (in terms of PV/VG) and I am getting about 130 puffs per tank! I know that juice has an effect on this too but does this seem right?
