I have a Nano and use it daily. Much smaller than the mini sub but no rba deck. There is a new one coming out that does have the rba deckj.I tried to like dripping, but just don't! My kayfun just sits here looking big.....I picked it up to show someone the other day, and that thing is heavy! Good ole' Aspire minis including the Nova and GS Airs.......best clearomizers in a very long time!
With all of that said, I'd be willing to try a Nano!
