I usually use a rba but I tried one of these to see what the buzz was about and to be completely honnest, I wasn't happy with the flavor either. It seemed muted to me. Especially compared to the rba. However it did give decent vapor. But mines sitting because of the flavor issue. I'm suprised we are the only two who has said anything about this.
Hmm this is just imo but I don't think you can compare a rba with the aspire nautilus
They are just worlds apart I think
