I dont use Watts, although I have a couple of 300.00 plus Mods that will do VW.....and use to own two SVD's (which are still in use today by family members...both right at a year old)....... so I do think the SVD is a great mod. My favorite for the price.
I learned with the SVD that in VW mode, your battery gets used up quicker because its always "self adjusting itself", so I quit using it along time ago.
So, if your using Volts or Watts....who cares. Its the Same power that you "settle into" in the end.
Back to your question...Provari..Why ? Everyone has really answered this for you, and yes, the taste is better due to the chipset, etc, etc.
Ive only found one mod that will compare, and it has to be used in Hybrid Mode and only with a Kayfun original 3.1. This set up will run your about 475.00 and wont go into that in this thread.
I love my "other mod" that I use and use it most of the time, but will say this. If I was given a choice of only one mod.....to choose to have cause im gonna be stranded on a desert island (with a charger, lol) and all that jazz.. (you know the old storey) I would choose the Provari over anything out there without blinking my eye. In a heart beat. Period.
Do you need to buy one ? Of course not
Will you regret it? Not one bit........and I wont sell you mine.
