The included atty is a pleasure to build on—lots of room, easy to wick—but the draw is MUCH too airy for my liking. I prefer a tightish draw, about like the cigarettes I used to smoke. The upper airflow control (if you could call it that) takes pliers to turn and doesn't make much difference anyhow. No matter how I adjust it, this thing is still a lung-hitter's dream. Too bad, because otherwise I might like the atomizer. As it is, I won't be using it.
The mod itself is simple & solid enough, but the chrome finish is far more annoying than I expected. Even my chrome VTR wasn't this bad: I'd swear it smudges if I so much as glance at it.
And yes, the bottle is a pain to install & remove. If I intended to use it much I'd try to limber up the bottle threads by dabbing some abrasive compound on them & screwing a spare cap on & off half a dozen times. Might smooth things out a little, I dunno.
I hate to sound like yet another Reo fanboy, but this mod will gather dust unless & until my faithful old LP Grand starts acting up…though in the six months I've had mine, it hasn't even hiccupped.
On the other hand, if you like a wide open draw & don't mind wearing cotton gloves when you vape, the S-body is a pretty decent mod & seems like good value for the money.
