I began my vaping journey two years ago with a well-respected and popular e-cigalike setup, but after only 3 weeks I was unsatisfied with the poor battery life and the limited selection of juice attachments. I skipped right over the intermediate eGo battery setups and went directly to a mechanical mod topped with a cartotank.
A visit to a vape shop allowed me to experience variable voltage for the first time. The owner put a Kick drop-in module into my Silver Bullet, and I was amazed with the difference it made my juices taste. I went on a serious research quest for variable voltage mods.
I chose to get a Provari, which was regarded to be the best variable voltage mod on the market. I was not disappointed. I ended up having a total of three Provari's. Yes, to me they are well worth the money. I've accumulated a dozen mods over two years time (including mechanical and VV/VW mods), and continue to use my Provari's 90% of the time.
I was gifted a Kayfun Lite Plus rebuildable tank atomizer about two months ago. This has become my primary juice attachment for its great flavor production, ease of setup, and consistancy.
Not a fan of dripping or cloud chasing, I prefer the convenience of a tank.
So long story short, my favorite setup is a KFL+ with a Provari.
Juice-wise, I seem to be gravitating to vendors who use all-natural, all-organic flavorings. I still use a 50/50 pg/vg ratio. I have begun experimenting with some DIY e-liquids.
