hey,I also use DC on provari, you need to get used to how to use them.
I have both metal and clear ones, for some reason clear ones are much better, the go higher on voltage and not burning.
the metal ones you should use on 3.6, 3.7, 3.8 and dont go higher, i filled a brand new one and it was burned on 3.9.
After i disassembled it, it wasn't burned much just a bit but enough to make your juice taste like burned fabric..
And the metal ones are single use, you can disassemble teh clear one and use again, even if you burn them, you just clean the burn spot, or replace the fabric that goes around the coils from used cartomizer (not the filler material)
The clear ones work fine on 4.2. on 4.3 they give errors from time to time and on 4.4 they wont fire.
We need GV to stock some HV merch

many people using 5V and higher these days, I hope they make a dual coil with 2 2.0 ohm coils or 2.5 ohm coils, it will be amazing for ProVari
Glad to hear it, because I just received dual coils, and on my ProVari they are aweful!
Not sure how well they work on other devices, but it was basically money down the drain for me.
I'm now waiting for the Vision Clear Carto, and hope it'll work much better!
(Partly my fault, guess I should have checked how well the dual coils work on a ProVari....)
Live and learn.
