I'm quite happy with everything the REO offers, the only drawback, which is probably a user error haha, is that the amount of vapor it's producing? I'm using a boge 510, LR atty, with a 50/50 mt baker vapor ecto-cooler, my 80pg/20vg juice on my MVP produces much more vapor than my REO. Not sure what the problem is, I even tried a 20/80vg cherry limeade on my REO, and still the vape production isn't quite satisfying. Is it the atty? Do I need to move on to an RM2? Thanks ! Happy vaping
