have had the reo now for a week or so. although it is an easy device to run there are some little tricks to get the reo performing the way it should and I do believe I have figured these out. it is now performing better then any device I have ever vaped, period. been vaping a couple years and most of that time was genesis devices. I have done just about every possible set-up with them, with every wick, with every wire, and every resistance. I have had many mods, from caravelas to egos. well this reo absolutely blows the doors off of all that. along with the reo, the rm2 and the micro coils I am in vape heaven. thanks
