I am going to pick one of these up very soon.
I moved from the RM2 to the Odin and then to the Derringer. This design appears to combine the best of both as well as the addition of top air flow for less leaking. RxW is less absorbant than cotton in the rda as it takes up less space and I often have a small pool of liquid sitting in my rda from over squonking. If my Reo gets tilted even a bit, juice just runs out like a fire hose.
Look for a Reo Mini /RM2, an Odin and 2 Derringers in the fs/ft soon!
My thoughts and my atomizer journey are similar, RM2, Odin, Derringer with an Igo and RM3 thrown in because they seemed like a good idea at the time. After the Derringer, I went back to the Odin. I like the free draw of the Odin and Derringer but as the founding member of "Over-squokers Anonymous" my Derringers I were flooded and they leaked - the Odin is a more forgiving of my squonk affliction. In addition to helping with flooding, this RM7 looks to me like it would be an easy build and then an easy re-wick with the coil in place. I may regret not getting two, one for each hand and each Reo.
