I would like to say that when I first started vaping I bought all sorts of pvs. Evic, reo mini, tons of egos, few rbas, zmax, provari w/ zatty pro. I am back after months of trying every other one and would like to report that the reo mini 2.1 is my favorite. I'm running .5mm flat wire at 1.2 ohm on 4 wraps and a cotton wick. Beast....this is a beast. Love it. Really works well with grants vanilla custard, and with the cotton wick there's not a single person who's tried it that hasn't been in awe of how good it tastes and how well the device works. So you could say after spending 2 grand on devices I've found that I'm happiest with this one.
