These topics always explode... LoL
I, like many others here, have owned a variety of devices over the time I have been vaping, to include the ProVari...
I started with cheap eGo batteries, and I thought they were great.
Then I got a Twist, and what a difference VV makes!
Then I got a Lavatube V2, and I thought it was the best thing out there!
Then I got a Vamo! Holy Variable Wattage! Awesome!
Then... Out of curiosity, wanting to see what all the fuss was about... I got a ProVari from the classifieds.
I haven't used any other APV since that date...
I've tried a few mechanicals since I got the ProVari, but I always seem to go back to the ProVari.
Now, this is where the subjective opinions come in to play, so I preface this with, this is my opinion only! LoL!
I find that the ProVari is built better than any other APV on the market. Better materials, better craftsmanship, better threading, better finish. Also, I find that the ProVari delivers a smoother vape than other comparable VV mods.
Now, your mileage may vary, of course, but most opinions of the ProVari that I have seen in my time on these forums are similar to my own. People get them, and they love them.
All of the other mods work, and they typically work well. The ProVari does everything those other mods do, but just a little bit better. And that little bit, IMO, make it worth every penny...
