I guess the REO is really the best answer. once i get coil building down i'll get one with a reomizer topper. Then i suppose i can just redo the wicking daily and rebuild the coil every week or two or i've seen some say they only do it once a month.
well...i use a protank with a 2.0 coil mainly, sometimes 1.8 or 2.5.
I have this IGO but I still haven't done a lot of coil building, but I have a coil someone made me and i just got some cotton and wire. I love the taste but hate the fiddling and the IGO is messy too.
As adventurous as you are firephly, I just assumed that you already knew how to rebuild, lol. I replace the coil on my a7 anywheres froim 1 week to 1 month after I install it.. Depends on liquid, some will wreck your coil quick, lol. Bobas bounty is one. MBV cookie blaster will do it in fast. The darker the liquid the less coil life you'll get is the general rule. You will have no problems rebuilding, I'm sure
As far as a REO goes, I used to think it was stupid to pay this much, and look at all the things my zmax can do that a reo cant.. That was early on in my vaping experience and I hadnt a clue what I was talkin about yet, lol. Know that I've had some time to form an educated opinion(instead of goin for the one that looks the coolest or has all the different bells and whistles), I chose a reo because its solid, reliable, and doesnt oxidize my juice or need to be dripped every 5 puffs. Low maintenance, reliable, durable.
