I've had my MVP 2 for maybe a week. I'm mostly using EVOD's and mini Protanks with resistances ranging from 1.8 to 2.5, and I've found that on variable power I don't have to adjust it very much between different resistances. I'm mostly staying between 6.5 and 7.5 W. It also depends on the particular liquid, what temperature produces the best flavor. I've also been using the iClear30 that came with the MVP - it's 2.1 Ohms - I put a root beer flavor in it and it's been good at 6.5 W. BTW, when I first filled up the iClear, it was leaking like crazy - it seems like I can't fill it up over the 2.5 mL line or it will leak; has anyone else had this problem?
I also have some questions for MVP users - I got mine from FastTech, and I'm wondering if it's performing exactly the same as everyone else's: about how many puffs are you getting per full charge? I seem to be getting between 650 and 700. The battery meter starts out at 4.2 (green light), and I get past 600 puffs before the light turns yellow at 3.7, then I probably don't get more than another 50 puffs before the light turns red, the meter reads 3.2, and it shuts itself off. This seems kind of strange - is it normal? Also, these are minor concerns, but in the instruction book it says that when you hit the P and U buttons at the same time, it will show the atomizer resistance, the battery voltage, the number of puffs since turning it on, and the current Voltage or power setting - mine just shows the first two values. I can only get the number of puffs by holding down one button or the other for a second, and I have no way of checking whether it's currently on the VV or the VW setting. Also, the book says that when it displays resistance, it will show an "R" followed by the ohms reading - mine shows an "A" (presumably for "atomizer"). Just kind of weird. Also, even though the passthrough function works fine, the buttons and display usually will not do anything while it is plugged in.
