It seems I've taken the average path in Vaping. I started out about 18 months ago with Blu Ecigs and QUICKLY moved on to EgoC's then again quickly to Ego Twist's. A couple of months ago all three of my Twist's seemed to lose battery life quicker and quicker. I went to my local Vape Shop VaporEscence and told them I was ready for the next level and I just wasn't getting what I wanted out of my Ego's. After much education I jumped in with the Itaste MVP 2.0 w/ IClear 30. I really like it but noticed what the guys at Vaporescense were using. I did some research on the Provari on this forum and other places and decided that today was the day to dive into the BIG NEXT LEVEL. After a thorough description of the Provari and what was required to use it, I decided to invest in what I think may be what I have been looking for. I bought the Provari along with a KayFun tank, wire, cotton, two Efest 2250 IMR18650 3.7V batteries and the charger. The guys at VaporEscense have always been very helpful and today was no different. They patiently walked me through the process of how to build my own coil etc. to run in my KayFun. Very cool process. Anyway, this thing rocks. I have absolutely no regrets on spending the money!
