I may just get shot for saying this but the Darwin is hands and fists above the provari. Just try putting a LR atty on it to figure out why. And before everyone goes all Provari on me I do own both and while the Darwin does have its own flaws, the provari is my backup to my Darwin. But to each their own.
Darwin looks very nice, but I can't get past a Darwin with a
tank on it.
After two years of vapping, I much prefer using a
tank... Mom and Pop Submarine Mini, Lava
tank (obviously, my favorite...), a MAP tank... but it HAS to be a tank!
Forget cartos, dripping (unless I'm at home, and want to switch flavors)... when I'm out and about I NEED a tank.
And a Darwin, with a tank, simply isn't very practical to carry around.
ProVari, also, hasn't proven to be the easiest to carry around, so I now use my ProVari mostly at home, and a Box VV mod when out and about.
Waiting for a wood Variable Volt box mod to replace my el-cheapo MadVapes box, but I happen to really like the MadVapes, and it was inexpensive!
Hey... it's great that there are so many choices available.
