I have a truckload of clearomizers. The only system I was every 99% satisfied with was carto tanks. I have zero nic in a few of them for my wife to use. She's extremely casual about vaping, was never a smoker, and I think a Reo would be a bit over the top for her needs. Of course that doesn't stop me from thinking about ordering one for her. i'd let her try one of mine first though.
Funny, that's about the same story with me. Wife never was any kind of a smoker, but I bought here a little ego c-twist with some fruity zero nic juices. She will pull it out on occasion when she has a sweet tooth and is avoiding candy/sweets. Every so often i'll try to get her to take a drag off one of my mechs, she rarely does it because she's "scared" (virgin lungs lol). However, she has done the Reo a few times and REALLY liked it. As we know, the flavor on a reo/rm2 BLOWS away the flavor out of any carto/clearomizer. I have thought about getting her a Mini, but to my knowledge you cannot get a RM2 on there, so that kind of defeats the purpose. I may just buck up and get her a grand, wrap is a nice mild, 1.5-2.0 ohm coil so she can actually get the most out of her vaping experience.
When I decided I was going to trade/sell my Reo the first time around, she told me, "No! Don't do it, you will regret it". I had no idea why she was saying this as she hardly knows schitt from her shoes when it comes to vaping. Apparently she was observing how I would always go back to the Reo (despite TRYING to not like it

). When I re-bought my newest Reo, I got the ol' "I told you so" treatment.
One of the many great things about the Reo is the flexibility in vaping styles, so to speak. No matter how aggressive (or not), you like to vape, there are options. As much as I do like some of my Tubed Mech mods (appearance wise), there is simply no Chi You that has a 'feminine' twist to it like the Reo's have, if wanted. It took hundreds and hundreds of dollars, testing out the vaping market for me to come to the conclusion that you simply cannot go wrong with a Reo.
