I went from the MVP & VV3 to the istick. Love it. Nearly as much battery life as the mvp, and it's tiny.
Only complaint is that voltage is measured in vavg, not rms. 3v on the istick is around 4v rms, with the difference narrowing as you get closer to 5.5v.
Imo, this makes wattage mode pretty useless. I just leave it in voltage mode & adjust to taste. Or occasionally do the math to work out actual wattage.
Overall, very happy with it despite the above. Other devices I'm curious about now are the mvp3 & rdna40.
