Reo mini 14500 are really special. Its a tiny little mod. Even with the 510 to 510 an a full sized A7 its smaller than my provari mini with tank. I just wish I had thicker kanthal because 2 wraps and I'm already at 2.5 ohms with the kanthal I have left -___- I am thinking about saving for a reo grand or a VV reo grand, I think I am into VV because I can wrap a high resisted coil and up the voltage. The Vmods have the plastic that I have seen broken and read too many stories about it breaking. If the Vmod was all aluminum for under the price of the reos or at the price its at now, would probably consider it or I'd probably have one instead of my reo mini. But I dont think I'll find a cheaper all aluminum bottom feeder. My reo never leaks in my pocket. But i dont usually need to put it away with juice in the catch cup. With an RBA I just squonk until the cotton by the coil is wet and then I vape until I get less vapor and squonk again or put it away. If I'm not mistaken, an A7 will not fit in the Vmod's collar? Does the Vmod stay together without the collar screwed down? Idk. I like Reos. I have so many tube mods.. But I'm thinking about selling some. Or I'd like to just save up some $$ and buy a VV ReoG or Grand because I like my mini a lot. Plus, if I was using cartos or a 510 atomizer, I might get a drip shield. With a shorty carto or atomizer, u just need an unsealed 510 to 510 connector and a drip shield and you shouldnt get much leaking, right? The juice well is basically covered by the drip shield. I think the Reos are the most versatile.
