I don't have the mini or the RBA deck so I can only comment on the coils, but I think they are fantastic so far. Only day 2 of using them, but the flavor is great and lots of dense vapor. This thing guzzles up juice like crazy too! I want to get the mini to rebuild on, but I'm wondering if I'd even want to since the stock coils are so nice. All of my rebuilds just never seem to hit as good as a good coil, it's probably my own fault but even when trying to rebuild or rewick a stock coil, I end up with wicking problems and dry hits and just not quite the same as a brand new stock coil. But its nice having the option of going "Ok screw this crappy build!" and slapping a new coil in the tank and back to vaping again.
That being said, does anyone know if there is word on whether or not they will have a RBA option for the nano? And where is the cheapest place to pick up a subtank Mini at this point? I see them for about $35 most places, wondering if there is a better price somewhere? Otherwise, I guess I'm okay with just the nano for now... and maybe wait for a price drop.
