I've never been much into the hobby aspect. Back when shipments were getting confiscated in late 2009/early 2010, my mindset shifted to preservation, only wanting devices that I could fix myself if need be. vaping worked for me, and I wasn't about to let anyone take it away. The REO fit the bill perfectly, an industrial-strength device that I could repair myself, and I was already sold on bottom-feeders. I got one of the first Mini run and one of the first Grand run. I added more over time, and have 9 REO's. And the advent of rebuildable atomizers was an incredible boon - I did watch this with great interest. Over the years I bought a few other devices, tanks, etc. and they've all mostly been "meh". I did buy 4 Coppervape bottom-feeders this year, as they fit my criteria, and the price was too good to pass up - I've been very pleased with them. Between those and the REO's, and a bunch of BF atties, I'm set for several lifetimes.
