I too have to cheer for the reo. My first mod was a phidias and it vaped great and took an 18650 battery and all, but you had to tip it just like the rev 2. That got to be a hassle occasionally cause I'm a short girl which equals puny little hands. Not that great when your driving with one hand and trying to flip something the size of a pack of smokes over to feed more juice.
The reo is easy. I don't even have a problem with the size of the grand. Other features that I'm grateful for is that since its fully mechanical there will never be a worry about frying any wires or connections. Its the only mod (that I know of) that can be submerged under water. Being adonized metal, juice sitting in the catch cup wipes clean without eating away at the finish. If I drop it (been there, done that many times now) it won't break. Hell, someone even ran theirs over with a car and it still worked.
