Yeah I give a lot of credit to hardcore smokers that have been vaping 2+ years. Seems like the technology and equipment has traveled to the current point in time at the speed of sound, I can't imagine the hassle of vaping even two years ago.
I bought a set of cig-a-likes 3 years ago at a Mall cart--that were way over priced. After one week I said this isn't worth the hassle and put them in a drawer. This past winter I was in a situation that made it very difficult to smoke, so I went to a drugstore and bought another system. The batteries lasted about 15 minutes and when they would die--I grabbed my cigs. So they did not really do any good as far as quitting.
In June my friend introduced me to the Vision Spinner and some Kanger T3's--within one week I was down to 3 analogs a week. Another week--totally quit!
I am still on 'finding the right juice journey'--I know I will find that right one and all will be well!
For me it was the flavors. ..I am amazed that I spent 20 years eith the same taste and now I can just change an atty and get a Whole new taste...heck push a button and get a hotter vape...
