I've had my REO for a few days now, and let me start by saying that I LOVE this mod!!! No more dripping or refilling for the fresh juice vape, this beauty feeds the juice to the carto or atty with just a press of a button. With the 18650 battery and the 6ml juice bottle, you can go a couple of days without doing anything but pressing a button vape. This is the easiest mod I've ever used, without a doubt this is low maintenance vaping.
When I'm on the go, only thing I worry about is battery failure. So now instead of carrying a couple of mods, extra juice and batteries when I'm out and about, it's just me, my REO and an extra battery. No more hauling around several mods and stressing over something failing. Now it's as simple as when I smoked analogs and size wise the same too, the REO is just a little smaller than a pack of cigs and extra battery is about the size of a lighter. Did I mention that I LOVE the REO!!!
I've heard and read that some may have issues over the size of the REO. Really?!?!?! I'm a small woman, only 5'4 and weigh 120lbs with small hands and the REO fits me like a glove. I one hand this device with ease, hold in palm and press juice button with thumb and power switch with my index finger without any struggle.
I toss it in my purse, takes up less room in there than a pack of cigarettes. I can even fit it in my jeans pocket just fine too, and I'm a size 4. It is solid and therefore I don't worry about breaking it either.
For those that worry or fret about the size of the REO, can I ask WHERE you carried your pack of cigarettes when you out and about? You carried them somewhere on you. I know that if my purse wasn't big enough to hold my wallet, cell phone and pack of smokes, I'd just buy a bigger purse as there was NO way I was leaving the house without those items. LOL Same with the REO now, I'll never leave home without it.
So I guess in a nutshell, the REO is no bigger than a pack of cigs, is a solid and ain't gonna break girlie mod (although it is beautiful) and you don't have to pack up your entire ecig collection and accessories for a 2 hour trip. And my opinion, if there is a downside to this mod, I haven't found it!
