Howdy, saw this subject and just had to comment. I am a relative newbie myself though I started with disposables late last year. I got my Ego-C kit (EcigXpress) approx. a month ago - a couple weeks later I bit the bullet and ordered my Provari. (BTW - Talk about fast delivery, I ordered my unit on Friday and received it the next day! it turned out that Pro-Vape is in the same state, but still - that is a lot better than my HMO does with vital prescriptions) The Provari has become my home/desk vaping unit. I usually use it only for dripping. NOW, I am waiting on a couple of tanks for it because I'm already tired of dripping 2-4 drops at a time, especially when I am busy around the house. Like a lot of the videos I've seen I use the Provari in drip-mode to test new flavors - carts or e-liquid. Using it as I do (so far) I don't feel the need for the larger battery option - though I have three of the regular ones. One more thing - I purchased the car-charger with my ProV - haven't even unpacked it yet.
My Ego-C and Twist batteries all equipped with clearomizers come with me when I leave the house. I use a neck-strap on the Twist battery but otherwise people don't even notice what I am "smoking". I was at a casino this weekend where one lady commented that my cigarette smelled like maple! I have a two outlet usb adapter in the car and that does me for driving trips very nicely.
To be clear - I like my Ego-C, I admire my Provari because it impresses me with it's consistent performance. This is my vaping setup for now. NEWBIES - keep at it you will find a good combination of hardware and flavors that will work for you. I tried to start super-cheap and wound up spending more money than I should have - don't believe everything you see on YouTube.
