I'm much more of a tank user, I have a haze rda which is ok, and I did pickup an alliance v2+, because it's a steal for 50 bucks imo, and with some big claptons it's pretty insane, but I only use it occasionally on the weekends, and back to my mt, Bellus, and aromamizer.  I just bought another mt today with the money I was gonna spend on the crius, but I think the crius needs a few tweaks, but it looks like a promising rta... Mt is the only one I own 2 of!  So that says something.  The juice wells are the trick, stuff them full, they are big enough the same wicking works for Max vg or 50/50, that's the beauty of this tank.  All the others take different wicking methods for different viscosity juice!   My first mt was defective, btw, it literally fell apart within a week, but I returned it and quickly bought another one.  It's that good. Internet pic of the alliance v2 below if anyone hasn't seen it, it's awesome
