Oh gosh. I started dripping in 2011. Back then it was with a Joytech LR 510 on an eGo battery.
Then came the 1.5ohm HH 357 on a ProVari. Cleaning the damn things every day got old really fast!!
By the time 2012 rolled around RDA's were popping up everywhere, and I tried most of them.
Hated the leaking little suckers, and trust me, if you fall asleep with one lying in your lap ..... they leak!!!
But then I discovered the lil A7 RDA, and have never looked back.
I'll turn 84 next month, and I still wrap my own coils; and DIY my own liquids, and I still drip !!
Everything I use is over 10 years old, and none of it is even made anymore. (except wick & wire)
32ga Kenthal A1 still works, and silica (Ekowool) wicks still work.
