I have two Reos in addition to more than a few mech mods and they both have their place. If I'm sitting at my PC or watching TV, I probably have a Simplicity or Atmizoo with an rda in one hand and a bottle of juice in the other. If I'm outside throwing a tennis ball to my dog, or driving, I probably have a Reo. The tube mods seem to produce a bit more vapor, but they both hit great and the Reo is a fantastic, hassle-free mod. I think everyone should try a Reo at least once and decide for themselves. For me a Reo is part of my regular vaping gear.
