Sorry kids.
Having a degree in Aviation Electronics from the United States Government and qualified to work on our highest grade Military Aircraft I can assert without hesitation that electricity is electricity.
A brand name does not impart any magical quality that gives one particular product superiority over another.
If you dial in the voltage and the amperage I don't give a crap what product you use, as long as you are comparing the same vehicle (delivery system) side by side there will be NO difference.
The Provari might be more consistent then another particular electricity source. But the facts remain the same. Voltage is Voltage. Amperage is Amperage.
Anything that puts out the same Voltage and Amperage is going to be identical in function.
Let me guess...........you don't own a ProVari nor have you EVER used one?!
You may be qualified to work on our highest grade Military Aircraft.
I'm qualified to work on my highest grade ProVari vape!
