My personal take on the issue (Being new and uninformed as to details), is that its not that VW would be hard to add as a feature, or that it wouldn't sell. As good as the Provari undoubtably is; there is always room for improvement (If the voltage selection feature round-robins, why the need for seperate Up and Down menu options? for example). The company has a good solid product and is trying to avoid the trap of Product Churn, wherein they release upgrade after upgrade and risk damaging the good name they've built up from the community. How long ago was the 2.6 version released anyway? They'll probablyr release a 3.0 version as soon as the current one begins to show its age a little more.
Stop worrying about the numbers and vape to taste
I like the LED screen vs OLED - maybe because I'm old enough to remember when 7-segment LEDs were all we had. I really like it.
No VW, no puff counter, no rotating and vibrating tip, no ProVari for me!
