We must disseminate what we know about the Provari and why it is, to many vapers, new and veteran, considered to be the be-all-end-all of APVs. I hesitate to call it a mod because nothing has been modified.
1. USA built.
Amurrica! Yes, it is 100% built in America. It has a lifetime warranty (correct me if I'm wrong)
2. The durability and the quality of the product.
I do not own one, but I've handled many, and it is a very sturdy piece of machinery. It will take a lickin' and keep on tickin'.
3. The consistency.
It has super-fancy chip technology that will give you that perfect vape up and until it's time to change the battery.
4. Variable Voltage
This is arguable since a lot of APV's (hell, almost all of them) offer VV. The batteries range from 650 mAh Kgo VV's to Twists to Spinners to who knows what else. But with the Provari you're pretty much safe in assuming the volt you lock in is the voltage you're going to get. The Twist is acceptable, the Spinner, I can't say, I don't own one. [EDIT: Ohm check function. One of the greatest things ever to come out in the vaping world. I love this function. But now that I got it on my Vamo, I'm not too impressed -- unless the Provari's ohm checker trumps the Vamo's. I'm not an electrician or an engineer.]
5. Longevity
As
many others have said, you don't have to replace the Provari. Ever (fingers crossed). Just the batteries and the juice delivery system. With Twists, you might get a year, two years max from the battery. Then it's toss and replace. I'm not knocking the Twist, I
love mine. But as far as longevity goes, Provari > Twist.
I say all these things not owning a Provari. But I've held enough, vaped enough, and been around enough Provari owners to understand their Provari "....".
I'm a nerd. Before I collected PVs, I was obsessed with samurai swords. It was a huge learning curve also. Lingo. "Rat-tail wallhanger" < "battle-ready full tang". "Stainless Steel" < "carbon steel". Fake "hamon" < real "hamon". "Musashi Economy" vs "Paul Chen". I started at the bottom and worked my way up. Now that I have a considerable samurai sword collection

:snort:: :

ushes glasses up:

, I'm focused on PV's.
I totally lost my train of thought so I'm ending this post here...
