I have been vaping since Feb 10th 2012. I started out with the Halo g6 and then the Vmod XL and then the 2.0 and then the Rio Grand. I was just not getting 100% satisfaction from any of these. So I bought a Provari with the 18650 extender cap. 5 volts is where it's at for me and after meals 5.5 is the spot. I bought the smoke tech 6ml tank to try before buying a more expensive one and found no need to buy a different tank after using it for a few weeks. I started out using 3ohm smoke techs with 3 prepunched holes in my tank and thought I would like the1.7s. I was wrong. The 3ohm are just what I need with my Provari and tank. I finally found the perfect set up!!!! I feel so free now from buying buying buying stuff trying to find the perfect vape. I use Dekang camel cut to 20mg with VG and don't feel the need to try anymore liquids. Before the Provari entered into my life I was beginning to think I would go bankrupt before finding what truly worked for me. As soon as my 2nd Provari (on order now) gets here I can start my new vaping life of just reordering what I know works flawlessly for me. Smoketech 6ml tank with 3ohm single coil filled with 20mg Dekang Camel and topped of once daily on a Provari with 18650 extension at 5 to 5.5 volts. I change the battery once every evening. It's fiddle free and 100% satisfaction. Whats your story of finding the perfect vape?
