I'm a bit embarrassed to say that I haven't had major problems with any of my gear. Of course I've had things taste burnt and leak at times, but I like puzzles. I've taken clearos apart that weren't designed to be, cut open cartomizers, pulled little plastic bits off all trying to figure out how they were supposed to work and why they didn't.
I started with a Green Smoke kit, but returned it after a couple of days. I liked it okay, but they sent me tobacco flavor instead of the menthol I ordered. The tobacco tasted a little like coconut and I wondered if there might be coconut flavor cartridges somewhere. Google, Google, Bad Plan Green smoke, if they had sent me what I wanted, I'd likely still be using it.
I bought a 650mAh eGo kit and some 306 dripping attys after watching a video on youtube. It was the old foam filled cartridge/atty system. I liked it and I learned to drip with the kit attys and the 306s. I then wanted something that held more liquid, so I got some CE4s and a mini Vivi Nova. They leaked a little, burned a little, but I figured it out. I then, however, learned about "tanker cracker" juices. My favorite juice killed everything.
It was around that time I found ECF and Baditude walked me through putting a glass carto tank together, so I could vape my juice. It looked a little big on my 650mAh, so I bought a 1000mAh, then a Twist a few weeks later. That was all I used for 6 months.
At 6 months tobacco-free I wanted to give myself a special present. I did a lot of research and bought a ProVari. Outside of adding a couple of Protanks, that was my main set-up. I have bought other devices since then, but I bought them for fun, like my Bobo.
At one year I again want a special present and bought 2 bottom-feeders. I had never used one before and it seemed like a fun thing to try. I bought a wooden one as a piece of art and a Reo to use.
My eGos and clearos have been PIF'd for the most part, they all still work, by the way. I vape a ProVari with carto tanks, a Protank or dripping and I use dripping attys on my Reo (a couple of which are from my original purchase).
Long story long, and it's all about me, but I don't think my journey has been very complicated.
