Being of a somewhat scientific bent, I undertook to acquire, since my introduction to vaping in August 2013, at no little cost as many vaping accessories as I could afford to determine the best equipment to meet my needs. As many have done before, I moved from cig-a-likes to shiny mechanical tubes with a sorts of RBAs, RDAs, genesis atomizers, bottom feeding atomizers, high end and low end, DNA20(30) boxes, mechanical bottom feeders of various types including the Reo Grand and mini. After untold experimentation, I have to say that I agree now that Rob is a genius and that the Reo is a remarkably reliable and satisfying mod. I love the aesthetics of some of my mechanical mods (e.g. the Nemesis and the Chi-you) and some of the atomizers are marvels of machining and function (e.g. the Ithaka), but for sheer simplicity and the ability to work day in and day out with a minimum of fuss and absence of irritations (like leaking), the Reo is where its at. So thanks Rob for this little marvel of simplicity that just works. Nothing else comes close, and for once, all the hype is true....
