I quit back in 2009 using 808 batteries and carto tanks. I can't believe I was actually able to stay off analogs with those, but it worked and I have never gone back. Of course things have changed and I now have quite a collection of everything from Ego batteries and Ego-C tanks, itaste vv, mvps (v1 & v2), mechanicals, various box mods, and isticks with drippers, various Kanger and Aspire tanks, and rebuildable tanks (Lemo and Orchids). It's amazing how much hardware one can accumulate in 5 years of vaping !! But - it has kept me from going back to smoking so I'm not complaining.
